Bundespr"asident Professor Roman Herzog has personally expressed a most cordial welcome to all participants. The Congress will be held under the auspices of the International Mathematical Union and under the sponsorship of the German Mathematical Society (DMV), the Federal Ministry of Education, Science, Research and Technology, and the Senate of Berlin. This announcement describes the Congress and gives related information. It explains how to register and how to submit a short communication or a poster representation. It also contains the necessary forms for securing accommodation during the Congress. \tableofcontents \section{Location of the Congress} \label{A} \subsection{Venue} \label{A1} The mathematical tradition in Germany is linked to the International Congresses. Felix Klein at the opening of the Congress on Mathematics and Astronomy in Chicago 1893 stressed that the mathematicians must form international unions. At the second congress in Paris 1900 David Hilbert presented his list of problems, the third congress was held in Heidelberg 1904, and now the German Mathematical Society is happy to welcome you at the end of the century to Berlin. Berlin has a long mathematical tradition. Euler, one of the greatest mathematicians of all time, worked and lived here for 25 years. For the 19th century, names from Dirichlet to Jacobi, from Kummer to Weierstra{\ss} stand out. The exodus of mathematicians from Berlin because of the Nazi terror was dramatic and tragic. After the second world war the city was divided, and mathematics and all other sciences had to overcome many difficulties. Now the city is united again and promises to become a great mathematical center through its three universities and two mathematical research institutes. Berlin is known throughout the world as a political center, as a symbol of separation and then of unification. But Berlin is also a wonderful city with lakes and woods, historical sites and sights, museums and galleries, theaters and concert halls, and not the least, its famous nightlife. There will be enough to do and to see for everybody. \subsection{The Congress} \label{A2} The activities of the Congress are divided between two locations. The program of the first day, August 18, 1998, including the opening ceremony, will take place at the International Congress Center~(ICC). On all other days, the lectures, seminars and short communications will be held at the Technical University~(TU) which is situated downtown. The address of the Congress is: % \begin{quote} \ICM\\ c/o Prof.~Dr.~J.~Winkler\\ TU Berlin, MA 8--2\\ Str.~des 17.~Juni 135\\ D-10623 Berlin, Germany \vspace{-2mm} % \begin{tabbing} Phone:\hskip0,5cm\= +49~30~314-24105\\ Fax:\> +49~30~314-21604\\ E-mail:\> \texttt{icm98@zib.de}\\ WWW:\> \texttt{http://elib.zib.de/ICM98} \end{tabbing} \end{quote} \subsection{Deadlines} \begin{tabular}{rl} May 1, 1998 & Early Registration at reduced rate \\ May 1, 1998 & Submission of abstracts for\\ & \hspace*{2ex} $\bullet$ Plenary Lectures\\ & \hspace*{2ex} $\bullet$ Invited Lectures\\ & \hspace*{2ex} $\bullet$ Short Communications\\ & \hspace*{2ex} $\bullet$ Poster Sessions\\ May 15, 1998 & Hotel accommodation\\ June 15, 1998 & Cancellation (with partial refund) of\\ & \hspace*{2ex} $\bullet$ tickets for the opera\\ & \hspace*{2ex} $\bullet$ tickets for the tourist program\\ July 1, 1998 & Submission of manuscripts of\\ & \hspace*{2ex} $\bullet$ Invited Lectures for the Proceedings\\ & \hspace*{2ex} $\bullet$ Plenary Lectures for the Proceedings\\ July 15, 1998 & Cancellation (with partial refund) of\\ & \hspace*{2ex} $\bullet$ private accommodation\\ & \hspace*{2ex} $\bullet$ registration\\ \end{tabular} \subsubsection*{Further Deadlines} \begin{tabular}{rl} March 1, 1998 & Submission for the\\ & Session on Mathematical Software\\ April 3, 1998 & Submission of videos for the\\ & VideoMath Festival \end{tabular} \section{Scientific Program} \label{B} The final program will be available electronically by June 1, 1998. \subsection{Opening and Closing Ceremonies} \label{B1} The opening ceremony will be held in the International Congress Center (ICC) at 10:00 on Tuesday, August 18, 1998. As part of the program, the Fields medals and the Nevanlinna prize will be awarded. The ICC seats up to 5000 people and allows a good view from all seats. After the opening session, there will be a lunch reception at the ICC followed by addresses on the works of the Fields medalists and the Nevanlinna prize winner and the first Plenary Lecture. The closing ceremony, including the last Plenary Lecture, is scheduled for Thursday, August 27, at 14:00 in the main lecture hall (Auditorium Maximum) of TU Berlin. \subsection{Plenary Lectures} \label{B2} At the recommendation of the Program Committee, appointed by the International Mathematical Union (IMU), the Organizing Committee has invited 21 mathematicians to give one-hour Plenary Lectures. The names of the speakers, together with their affi\-lia\-tions and fields of research, are listed below. The Plenary Lectures will inform participants of major developments, problems, and trends in mathematics. The IMU General Assembly, the Program Committee, and the Organizing Committee have emphasized that these lectures should be comprehensible to a wide spectrum of mathematicians. All plenary speakers have agreed to prepare addresses for a general mathematical audience. % \begin{description} \item[\bfseries Jean-Michel Bismut] (Universit\'{e} Paris-Sud, Orsay, France): Differential Geometry and Global Analysis \item[\bfseries Christopher Deninger] (Universit\"at M\"unster, Germany): Arithmetic Algebraic Geometry, L-Functions of Motives \item[\bfseries Persi Diaconis] (Mathematics and ORIE, Cornell University, Ithaca, USA): Statistics, Probability, Algebraic Combinatorics \item[\bfseries Giovanni Gallavotti] (Universit\'a La Sapienza, Roma, Italy): Dynamical Systems, Statistical Mechanics, Probability \item[\bfseries Wolfgang Hackbusch] (Universit\"at Kiel, Germany): Numerical Analysis, Scientific Computing \item[\bfseries Helmut H.

Moser and will be delivered in the afternoon of the opening day at the International Congress Center. The other addresses will be given in the Auditorium Maximum (lecture hall H~105) of TU Berlin. The Auditorium Maximum has a capacity of 1200 seats. The talks will also be shown in an adjoining lecture hall via closed-circuit television, so that an audience of more than 2000 people can be reached. \subsection{Invited Lectures} \label{B3} Also at the recommendation of the IMU Program Committee, more than 160 mathematicians have been invited to give 45-minute lectures in specified sections. These lectures are intended to be surveys of significant topics in the respective area of research. The speakers have been asked to make their lectures comprehensible for the general mathematical community, and they agreed to do so. These Invited Lectures will take place in the afternoons of August 19--22 and 24--26, beginning at 14:00. The Invited Lectures will be given in several large lecture rooms at TU Berlin. % Usually there will be about six or seven lectures simultaneously. % The list of sections is as follows, where the number in parentheses indicates the expected number of presentations in that section. \begin{tabular}{rl} 1.& Logic (5)\\ 2.& Algebra (8)\\ 3.& Number Theory and \\& Arithmetic Algebraic Geometry (9)\\ 4.& Algebraic Geometry (7)\\ 5.& Differential Geometry and \\& Global Analysis (13)\\ 6.& Topology (8)\\ 7.& Lie Groups and Lie Algebras (10)\\ 8.& Analysis (14)\\ 9.& Ordinary Differential Equations and \\& Dynamical Systems (10)\\ 10.& Partial Differential Equations (10)\\ 11.& Mathematical Physics (12)\\ 12.& Probability and Statistics (13)\\ 13.& Combinatorics (8)\\ 14.& Mathematical Aspects of Computer Science (6)\\ 15.& Numerical Analysis and \\& Scientific Computing (6)\\ 16.& Applications (12)\\ 17.& Control Theory and Optimization (7)\\ 18.& Teaching and \\& Popularization of Mathematics (6)\\ 19.& History of Mathematics (3) \end{tabular} \subsection{Short Communications and Posters} \label{B4} All Ordinary Members (see~\ref{I1}) of the Congress will have the opportunity to present their mathematical work in the form of a Short Communication or a Poster --- provided that \begin{itemize} \item they have registered by May 1 and marked in the registration form, that they want to present their work, \item they have submitted an abstract by that date, \item their contribution has been accepted by the Local Scientific Committee. \end{itemize} Only one Short Communication or Poster (and thus only one abstract) is allowed for each member. Each Short Communication lasts 15 minutes including discussion. Short Communications are grouped into time slots of 45 minutes for three presentations. The rooms for Short Communications are equipped with a blackboard and an overhead projector. Each Poster session lasts 105 minutes; during that period the authors should stand by their posters and be available for questions and discussion. % Authors presenting a Poster are advised to bring the material of the Poster with them when they come to the Congress since no facilities for preparing posters are available on site. The size of the individual poster panels is as follows: width 180~cm, height 120~cm. The abstract for a Short Communication or a Poster must include the appropriate section number (see~\ref{B3}) and 1991 MS classification number (see~\ref{AMS}) so that the Communications and Posters can be grouped in a coherent way for presentation. Abstracts may be submitted in English, French, Russian or German. Abstracts of accepted Posters and Short Communications which are properly prepared and received by the deadline will be reproduced and distributed to all Ordinary Members when they pick up their registration package. The Local Scientific Committee will notify authors of acceptance/rejection of their contribution. Instructions on how to prepare an abstract are in Section~\ref{D3}. Abstracts which do not conform to the stipulated rules will be returned to the author for resubmission. Late papers will not be accepted. However, it is possible to present them in ad-hoc sessions that will be organized and announced during the conference. \subsection{Organized Sessions} \label{B5} We invite Ordinary Members to organize sessions of Short Communications on their own initiative. Such sessions and their organizers will be included in the final program %Once the local scientific committee has agreed, after a review by the Local Scientific Committee. Ordinary Members who want to organize such a session should contact the Local Arrangements Chair (\texttt{moehring@math.tu-berlin.de}) with their program and their request for time slots within the schedule of Short Communications. All participants of these organized sessions have to submit an abstract for their Short Communication as indicated in Section~\ref{D3}. The organizer of such a session should inform the Local Arrangements Chair about the submissions that belong to this session. \subsection{Informal Seminars} \label{B6} During the Congress it will also be possible to organize informal mathematical seminars on site. Ordinary Members who wish to organize such spontaneous seminars are asked to make all arrangements among themselves, and to request a room either in advance (\texttt{moehring@math.tu-berlin.de}), or during \ICM\ from the congress office or from the Local Arrangements Chair. Such seminars may take place during the afternoons. If the congress office is notified before 15:00 the previous day, an announcement of the seminar can be included in the daily newsletter to be distributed to all participants on the following day. \subsection{Special Activities} \label{B7} Various suggestions for sessions of general mathematical interest have been brought to the attention of the Organizing Committee. In accordance with IMU and the Program Committee, the Organizing Committee has opened a new {\it Section of Special Activities} to cover the most important topics. This section is not part of the official scientific program as specified by the Program Committee. The section is still taking shape. It will probably include % \begin{itemize} \item Sessions on \textbf{Mathematical Software.} \item A workshop entitled \textbf{Berlin as a Center of Mathematical Activity} organized by the International Commission on the History of Mathematics (ICHM). \item Talks, discussions, and roundtables related to \textbf{Electronic Publishing}. \item The \textbf{Noether Lecture,} a roundtable and a luncheon organized by a group representing \textit{Women in Mathematics.} \item {Further roundtables,} e.g., on educational topics, and other events such as the presentation of O.~Lehto's new book on the IMU. \end{itemize} % The Deutsche Mathematiker-Vereinigung DMV will present an exhibition on the suppression and expulsion of mathematicians from the Berlin universities by the Nazis. % There will also be lectures concerning the impact of the Nazi regime on mathematics. \section[Other Events of Mathematical Interest]{Other Events of\\Mathematical Interest} \subsection{Events for the General Public} \label{C1} The International Congress provides a unique opportunity to inform the general public about some of the recent developments and future challenges of mathematics. Planned are: % \begin{itemize} \item A special lecture by Andrew Wiles (Princeton), on the development of number theory in the last twenty years. \item Several lectures for a general, in particular, non-mathematical audience. \item The VideoMath Festival, where films of mathematical interest are shown. \item The exhibition \textit{Hands--on Mathematics,} aiming in particular at teachers and high school students.%\\ (``Mathematik zum Anfassen''). \item Small exhibitions related to mathematics, e.g. mathematical posters, mathematics and ceramics. \end{itemize} % The lecture by Wiles will be in the Auditorium Maximum at TU Berlin, August 19, 19:30. All other presentations will take place in the evening, August 21--22 and 24--28 at the Urania, a lecture institute of long tradition situated not far from TU Berlin. (There will be a modest admission fee for some events at the Urania.) The exhibitions will be situated in the Urania and TU. You will find a detailed program on the WWW-server by June 1, 1998, and in the final program. \subsection{Book Exhibitions etc.} \label{C2} Book, educational media, and computer software exhibits are located near the main lecture hall and in the large atrium in the main building of the University. They will be open on August~19--22 and~24--26 from 10:00 to 18:00, and on August~27 from 10:00 to 15:00. All participants are encouraged to visit the exhibits during the Congress. \subsection{Other Mathematical Conferences} \label{C3} Traditionally there are several smaller conferences scheduled at various places immediately before or after the Congress. Starting on page~\pageref{L}, you find a list of such satellite conferences (as of December 1, 1997), together with the addresses where further information may be obtained. Please do not direct inquiries about these conferences to \ICM. \section{Publications} \label{D} The material described in the items \ref{D1}--\ref{D4} will be included in the registration package that each Ordinary Member will receive at the registration counter. \subsection{Program} \label{D1} All Ordinary Members will receive copies of the official \ICM\ program. The program will show in detail the dates, times and locations of all Plenary and Invited Lectures. It will also contain a complete listing of all Short Communications and Poster presentations. See the \ICM\ WWW server, after June 1, 1998. \subsection{List of Participants} \label{D2} A list of all participants who have registered by July 15, 1998 will be distributed to all Ordinary Members. A list of all \ICM\ members, including their mailing addresses, will be kept at the \ICM\ registration counter throughout the Congress. Ordinary Members are asked to check their own listing for accuracy while they are in Berlin, as this list will be used to prepare the official list of participants for inclusion in the Proceedings and to prepare mailing labels for shipment of the Proceedings. \subsection{Abstracts} \label{D3} Abstracts of Plenary and Invited Lectures, Short Communications and Posters will be reproduced and distributed in printed form to all Ordinary Members at the beginning of the Congress. These abstracts will also be available on the internet under the following address: {\tt http://www.mathematik.uni-bielefeld.de/ICM98} Abstracts of Short Communications and Posters should be written in English, French, Russian or German and should have the following form (compare also the enclosed example): \begin{itemize} \item[--] Section Number (see~\ref{B3}) \item[--] 1991 Mathematics Subject Classification number (see~\ref{AMS}) \item[--] Name and affiliation of author(s) \item[--] Title \item[--] Abstract text (no more than 120 words) \end{itemize} \begin{center} \setlength{\fboxsep}{2mm} \setlength{\fboxrule}{.03mm} \textbf{\bf Example Abstract} \\[2mm] \fbox{\parbox{75mm}{\small \setlength{\parskip}{1mm} \textbf{Section:} 2 \textbf{1991 MS Classification:} 17, 18, 55 Loday, Jean-Louis, Universit\'e de Strasbourg, France: \\ {\bf Leibniz algebras and their (co)homology.} \\ A {\it Leibniz algebra} is a vector space equipped with a product satisfying a variation of the Jacobi identity: $[x,[y,z]]=[[x,y],z]-[[x,z],y].$ There is a dual notion in the sense of Koszul duality for operads.

These Proceedings will appear as a special volume of {\sc Documenta Mathematica} (Journal der Deutschen Mathematiker-Vereinigung), whose electronic version is available at {\small\tt http://www.mathematik.uni-bielefeld.de/documenta} \\or {\small\tt http://www.math.uiuc.edu/documenta} A printed version will be distributed to all Ordinary Members of the Congress (except for the student members). There will also be a free internet version under the above WWW addresses. \subsection{Daily News} \label{D6} A newsletter containing program changes, announcements of informal seminars and information of general interest to \ICM\ participants will be available each day at the TU conference office (H~2036). Parti\-ci\-pants with announcements for the newsletter should be sure to submit them to the conference office no later than 15:00 the day before. \section{Social Program} \label{E} \subsection{Opening Lunch Buffet} \label{E1} On August 18, from 12:30 to 14:30 (between the Opening Ceremony and the Afternoon Session) a complimentary lunch buffet will be offered to all participants. It will be served in the International Congress Center (ICC). \subsection{\ICM\ Party} \label{E2} The Organizing Committee plans to stage a complimentary party for all participants. It will probably take place in the evening of August 26, 1998 on the campus of TU Berlin. \subsection{Opera} \label{E3} On the evening of Sunday, August 23, at 19:30, a special performance of the opera \textbf{\itshape The Magic Flute} by Wolfgang Amadeus Mozart will be staged at the Deutsche Oper Berlin. For this performance, a large contingent of tickets has been reserved for participants of \ICM. The tickets are available in five price categories, with prices ranging from 52 DM to 88 DM. Participants who wish to attend this special performance must purchase tickets in advance --- using the registration form. \subsection{Tourist Program} \label{E4} Several excursions (bus tours) will be offered by DER-CONGRESS during August 19--26, 1998. For a description of these tours see Section~\ref{K2} Reservations can be made on the registration form; if seats are left, it will also be possible to make bookings during the Congress (please contact the Tourist Program counter at TU Berlin). All tours will start in front of the TU Main Building, Str.~des~17.~Ju\-ni~135. \subsection{Footloose Tours} \label{E5} To convey some of the many facets of Berlin to the \ICM\ participants, and in particular to {accompanying persons}, several Berlin mathematicians, their friends and spouses have volunteered to offer informal tours of Berlin including visits to special museums, sights, and shopping streets. The tours are free of charge, except for possible entrance fees. They will be announced shortly before the Congress by means of Circular Letters from the \ICM\ e-mail service. They will also be posted on the WWW-server of \ICM\ or during the Congress on an information board. It will be possible to register by e-mail. To maintain the informal character of the tours, group sizes are tightly restricted. Places will be assigned on a first--come--first--serve basis. \subsection{Activities for Accompanying Persons} \label{E6} Accompanying persons do not have to register, see~\ref{I2}. They are invited to participate in all activities of the social program. The Footloose Tours are especially planned for this group of visitors to guide them to nonstandard places of interest, to meet other people, and to explore Berlin in a casual way. Moreover, the events for the general public in the Urania, see~\ref{C1}, are also intended for accompanying persons with some interest in mathematics. \section{Travel} \label{F} \subsection{Passports and Visas} \label{F1} For citizens of the countries of the European Community an identity card is sufficient. Citizens of other countries must be in possession of a valid passport, and for certain countries visas are required as well. Please consult the German Embassy or Consulate in your country for details. We have contacted the German Foreign Office on visa issues and do not expect difficulties. If you need a personal invitation to attend the Congress, you can request an official invitation letter (see Section H.2). We advise you to apply for a visa at least three months before the date on which you plan to leave for Germany. If you have not received a visa one month before the beginning of ICM'98, contact us by fax or e-mail (SUBJECT: visa). In order to help you, we need the following information: name, address and date of birth, passport number, date and place of visa application. \subsection{Congress Agents} \label{F2} DER-CONGRESS has been appointed by the Organizing Committee to handle registration for the Congress, hotel reservations, etc.\ for all individual participants of the Congress. Please send all correspondence related to the Congress (inquiries, requests, etc.) to the official congress address, as indicated in~\ref{A2}. DER-CONGRESS can be contacted directly at: DER-CONGRESS\\ Congress Organisation\\ Bundesallee 56\\ D-10715 Berlin, ~Germany \begin{tabbing} Phone:\hspace{.6cm}\=+49 30 857 903-0\\ Fax:\>+49 30 857 903-26\\ E-Mail:\>\texttt{icm@der-congress.de} \end{tabbing} Participants from Japan are requested to contact the official ICM'98 agent for Japan who will forward the registration form to DER-CONGRESS: Nikkei Culture Inc.\\ Mr. Sumiyoshi \\ 9-5, 1 Chome, Otemachi\\ Chiyoda-ku\\ Tokyo 100, Japan\\[2mm] Phone: (03) 5259 2666 \\ Fax: (03) 5259 2664 \subsection{Arriving in Berlin}% \label{F3} Berlin is easy to reach by all means of transportation. It has three airports, \textbf{Berlin Tegel} (aviation code TXL on your airline ticket), \textbf{Berlin Tempelhof} (THF) and \textbf{Berlin Sch\"onefeld} (SXF). If you come to Berlin by train, you will arrive at one of the three main stations, which are \textbf{Zoologischer Garten} (in the western city center, walking distance to TU Berlin), \textbf{Lichtenberg} and \textbf{Hauptbahnhof} (both of them are in the east of Berlin and further away from \ICM\ activities). For more geographical details, see {\tt http://www.berlin.de} All airports and train stations are well connected to all main locations in Berlin by public transport --- Berlin is well served by a far reaching network of bus, U-Bahn (subway) and S-Bahn (inner city railway) lines. The standard fare for a single ride AB-ticket that is valid on all busses, subways etc. will be DM 3.90. You will need this only on your day of arrival, since with the congress registration materials you will receive your Local Transportation Ticket (see \ref{F4}). If you come by car, we suggest you leave it at the hotel and use the \ICM\ Local Transportation Ticket. There is ample parking space at the ICC, but parking is very limited at TU Berlin. Many hotels are in the Western city center, close to the \textit{Zoologischer Garten} (``Zoo Station'') Train Station, which is not only a train station, but also a U-Bahn (subway) and S-Bahn (inner city railway) station with good connections in all directions. (To get to TU Berlin, for example, you would take the U2 subway line, direction \textit{Ruhleben}, and leave it at the next stop, \textit{Ernst-Reuter-Platz}). In this section, we therefore explain how to reach \textit{Zoologischer Garten} from the airports and from the other train stations. %From there you might proceed by %taxi or even walk to your accommodation. To {locate} your personal accommodation or hotel you might try to consult the Berlin city map which is online at % \begin{center} \tt http://www.kulturbox.de/perl/berlininfo \end{center} % Detailed city maps (including a street index) are also posted at all bus and subway stations in Berlin, which could help you to locate your destination after arrival in Berlin. The main connections to reach the congress locations are explained in Section~\ref{F5}. \mbox{}\hrule\mbox{} {From} \textbf{Tegel} Airport: The two bus lines with the numbers X9 and 109 operate the route to the city center. The X9 is a so-called express bus, which is fast, but makes only few stops. (But it does stop at TU's U-Bahn station, \textit{Ernst-Reuter-Platz}.) The 109 bus is much slower, but it takes a route down \textit{Kur\-f\"ursten\-damm} which is nice and convenient for the many hotels on and near this (main shopping) street. Both lines pass or end at \textit{Zoologischer Garten}. Duration: approx.\ 20 minutes with the X9 and approx.\ 30 minutes with the 109 bus. \mbox{}\hrule\mbox{} {From} \textbf{Tempelhof} Airport: Take the U6 subway line, direction \textit{Alt-Tegel}, up to the \textit{Stadtmitte} station. There switch to the U2 subway line, direction \textit{Ruhleben}, which will take you to the \textit{Zoologischer Garten} station. Duration: approx.\ 30 minutes. \mbox{}\hrule\mbox{} {From} \textbf{Sch\"onefeld} Airport: This airport is just outside the city limits, southeast of Berlin. To get to the center of Berlin, walk from the terminal building to the S-Bahn station. {From} there the S9 line will take you to \textit{Zoologischer Garten}. Duration: approx.\ 50 minutes. \mbox{}\hrule\mbox{} {From} \textbf{Lichtenberg} train station: This station is in the east of Berlin. {From} there two S-Bahn lines, S5 direction \textit{Charlottenburg} and S7 direction \textit{Potsdam Stadt}, will take you directly to the \textit{Zoologischer Garten}. Duration: approx.\ 30 minutes. \mbox{}\hrule\mbox{} {From} \textbf{Hauptbahnhof} train station: This station is in the east of Berlin. Take one of the four S-Bahn lines operating from \textit{Hauptbahnhof} in the western direction, whose destination may be \textit{Potsdam Stadt}, \textit{Westkreuz} or \textit{Charlottenburg}. Any of these will take you to \textit{Zoologischer Garten}. Duration: approx.\ 20 minutes \subsection{Your Local Transportation Ticket} \label{F4} With your congress materials, distributed at registration in Berlin, you will receive a special ticket that is valid for all types of public transportation (\textit{Bus, U-Bahn, S-Bahn}) in Berlin and in Potsdam, for the complete duration of the Congress (Aug.~17-27, 1998). The ticket is included in the registration fee.

General information about hotels may be obtained from the \ICM\ WWW-site. If you want to request accommodation for the Congress via DER-CONGRESS, please notify that using the WWW or the attached registration form. Please note that telephone requests cannot be accepted. Your requests for hotel reservation will be processed as soon as the pre-payment of DM 420,-- per room, payable to DER-CONGRESS has been received. (This includes a hotel deposit of DM 400,-- which will be deducted from your final hotel bill, and a handling fee of DM 20,-- for DER-CONGRESS). Please note that when all the hotel rooms of a particular category have been booked, DER-CONGRESS will no longer be able to guarantee further rooms in a desired hotel category, and thus reserves the right to confirm reservations in another category. DER-CONGRESS will hand over the reservation lists to the hotels two weeks before the Congress. If changes should be necessary after that date, you are kindly requested to contact the hotel directly by fax, and to submit a copy to DER-CONGRESS. If you plan to arrive at your hotel after 18:00 on the scheduled day of arrival, please mark this on your registration form, as reserved rooms will be kept until that time. If it is necessary to cancel your reservation, you are kindly requested to cancel until May 15, 1998. Later the hotels may charge non-occupancy fees to the customer. Please understand that in case of cancellation an administrative fee of DM 50,-- per person will be charged.

Many of these rooms and apartments are equipped with TV and radio, and some also have a phone. However, most of the single and double rooms do not have a private bathroom.

At some apartments, you might have to pay a single fee of DM 40,-- or 50,-- for cleaning up after departure. In addition, some hosts would like to have a deposit in advance. Please be aware of the fact that some of the hosts may only be able to communicate in German. A reservation form will be sent out by DER-CONGRESS upon receipt of the handling fee. Please fill in and return this form by fax or regular mail to DER-CONGRESS. %As soon as the handling fee has been paid, you will receive a reservation form, which must be filled in and returned by fax or regular mail to DER-CONGRESS. The confirmation of reservation will be sent out directly afterwards, on which the address of the host is provided. To clarify all further details, such as time of arrival, payment conditions, etc.\ you should contact your host immediately after receipt. If you have not contacted your host four weeks prior to arrival at the latest, the reservation will be released without further notice.

Of course, pre-payment will be deducted. Cancellations of private accommodation will be accepted free of charge until July 15, 1998.

The Hamburger Bahnhof has approximately 10,000 qm of exhibition space for the Collection of Erich Marx. The Marx Collection is composed primarily of works by major artists from the past thirty years such as Joseph Beuys, Andy Warhol, Robert Rauschenberg, Cy Twombly, Roy Lichtenstein, and Anselm Kiefer. Above and beyond these artists, the collection shows also works by painters of the Italian Transavanguardia, of Minimal Art, and the \textit{Junge Wilden} (\textit{Wild Youth}) painters from Berlin. The renovation and partial rebuilding of the former terminal train station is the realization of plans by Josef Paul Kleihues. \begin{tabular}{@{}llr} Thursday,&August 20, 1998&14:00--17:30 \\Sunday,&August 23, 1998&14:00--17:30 \end{tabular} \\[1mm]DM 40,-- per person \subsection{Cancellation} \label{K3} {\small In case of cancellation of tours or tickets for the Deutsche Oper after June 15, 1998, the full fee must be paid.

Nevertheless, there will still be many mathematicians for whom participation is economically unaffordable. To help at least some of them attend \ICM, large support programs have been set up by the \ICM\ Organizing Committee in cooperation with the International Mathematical Union. These programs offer financial support for active young as well as mature mathematicians from developing countries and for mathematicians from Eastern Europe. Details can be found in the \ICM\ World Wide Web server. The costs of organizing an event such as \ICM\ in a big city like Berlin are enormous. To keep them as low as possible, the \ICM\ organization depends -- to a very large extent -- on the dedication, time, and energy of many volunteers from the Berlin universities and mathematical research institutes as well as on the help of many colleagues throughout Germany. In addition to working free of charge they often cover arising costs from their own or other sources. The Organizing Committee would like to thank all persons and institutions involved. Even with all this help, it would still be impossible to finance a large and costly event such as \ICM\ by registration fees only. The organizers are grateful to the \begin{itemize} \item[--]Bundesministerium f\"ur Bildung, Wissenschaft, Forschung und Technologie \item[--]Senat von Berlin \item[--]Deutsche Forschungsgemeinschaft \item[--]Land Sachsen \end{itemize} for their substantial financial contributions to the organization of \ICM. Generous support has also been obtained from foundations and companies. Sponsoring from industry is hard to obtain in economically hard times, and we are particularly grateful to companies who recognize the importance of mathematics. The final list of sponsors will be announced at the Congress and published in the proceedings volume. Up to now financial contributions have been obtained from \begin{itemize} \item[--]Allianz Lebensversicherung \item[--]Siemens AG \item[--]Stemmler-Stiftung \item[--]Silicon Graphics \item[--]Deutsche Telekom \item[--]Herlitz AG \item[--]Springer Verlag \item[--]Nikkei Culture \item[--]Minolta \item[--]Sender Freies Berlin \item[--]SUN Microsystems \end{itemize} We would also like to express our thanks for contributions from the International Mathematical Union, the Deutsche Mathematiker-Vereinigung, and the Deutsche Gesellschaft f\"ur Versicherungsmathematik. Donations have been given by many mathematicians from all over the world who particularly contributed to the funds for the support programs for mathematicians from developing countries and Eastern Europe. Finally, we would like to thank the state of Saxony, one of the sixteen German states, who helped to make the IMU General Assembly possible. \textbf{The IMU General Assembly will take place in Dresden, Saxony, from August 15 to 16, directly before \ICM.} \section{1991 Mathematics Subject Classification} \label{AMS} {\small \begin{tabbing} 11\quad\=Number theory\kill 0 \> General \\1 \> History and biography \\3 \> Mathematical logic and foundations \\4 \> Set theory \\5 \> Combinatorics \\6 \> Order, lattices, ordered algebraic structures \\8 \> General algebraic systems \\11 \> Number theory \\12 \> Field theory and polynomials \\13 \> Commutative rings and algebras \\14 \> Algebraic geometry \\15 \> Linear and multilinear algebra; matrix theory \\16 \> Associative rings and algebras \\17 \> Nonassociative rings and algebras \\18 \> Category theory, homological algebra \\19 \> $K$-theory \\20 \> Group theory and generalizations \\22 \> Topological groups, Lie groups \\26 \> Real functions \\28 \> Measure and integration \\30 \> Functions of a complex variable \\31 \> Potential theory \\32 \> Several complex variables and analytic spaces \\33 \> Special functions \\34 \> Ordinary differential equations \\35 \> Partial differential equations \\39 \> Finite differences and functional equations \\40 \> Sequences, series, summability \\41 \> Approximations and expansions \\42 \> Fourier analysis \\43 \> Abstract harmonic analysis \\44 \> Integral transforms, operational calculus \\45 \> Integral equations \\46 \> Functional analysis \\47 \> Operator theory \\49 \> Calculus of variations and optimal control; optimization \\51 \> Geometry \\52 \> Convex and discrete geometry \\53 \> Differential geometry \\54 \> General topology \\55 \> Algebraic topology \\57 \> Manifolds and cell complexes \\58 \> Global analysis, analysis on manifolds \\60 \> Probability theory and stochastic processes \\62 \> Statistics \\65 \> Numerical analysis \\68 \> Computer science \\70 \> Mechanics of particles and systems \\73 \> Mechanics of solids \\76 \> Fluid mechanics \\78 \> Optics, electromagnetic theory \\80 \> Classical thermodynamics, heat transfer \\81 \> Quantum Theory \\82 \> Statistical mechanics, structure of matter \\83 \> Relativity and gravitational theory \\85 \> Astronomy and astrophysics \\86 \> Geophysics \\90 \> Economics, operations research, programming, games \\92 \> Biology and other natural sciences, behavioral sciences \\93 \> Systems theory; control \\94 \> Information and communication, circuits \end{tabbing} } \section{Organizing Committee} \label{P} The Organizing Committee was set up in 1994 and has been growing since.
