#### 1. LETTER FROM THE PRESIDENT

Dear Reader,
Welcome to the second issue of IMU-Net, the electronic newsletter of the
International Mathematical Union.
IMU is very pleased with the positive reaction to the first issue, and
that a large number of mathematicians have chosen to subscribe to IMU-Net.
This is the last issue to be sent to the current mailing list.
So if you wish to receive further issues, which are free of charge, and
if you have not already subscribed, you must do so by one of the methods
described below.
IMU represents you. IMU-Net is designed to make that representation more
effective, by informing you about what IMU is doing on your behalf, and
providing information about current initiatives that will enable you in
turn to influence IMU.
I very much hope that you will become a regular reader.
John Ball
President, International Mathematical Union.

#### 3. ANDREY ANDREEVICH BOLIBRUCH

IMU is deeply saddened by the death on 11 November 2003 of Academician
Andrey Andreevich Bolibruch, of the Steklov Institute (Moscow, Russia),
who was a member of the IMU Executive Committee
Academician D. Anosov writes:
Andrey Andreevich Bolibruch was born in Moscow on 30 January 1950. He
graduated from the Moscow State University in 1975. Since 1990 his main
workplace has been the Steklov Mathematical Institute of the Russian
Academy of Sciences in Moscow; but from 1996 he was also a Professor in
the Department of Mathematics and Mechanics of Moscow State University,
and in 1999 he became an Honorary Professor there.
A crucial moment in his mathematical career came at the end of the 80's,
when he discovered that Hilbert's 21st problem (concerning a certain
class of linear ordinary differential equations in the complex domain)
generally has a negative solution. This was an unexpected and brilliant
achievement. For a long time people were convinced that at the beginning
of the 20th century Plemelj had obtained a positive solution to this
problem by reducing it to another of his results. Several years before
Bolibruch's proof, it was discovered that, although this other result
is correct, the reduction does not always work. However, people continued
to hope that the answer to the 21st problem was positive. Thus Bolibruch's
result was unexpected and made a strong impression.
After this, Bolibruch's scientific work was related to this problem in
one way or another. He also studied its connections to other problems,
e.g., to the problem of isomonodromy deformations, which became important
at that time for other reasons. He wrote about 70 articles and several
books.
In 1994 Bolibruch was elected a deputy member of the Russian Academy
of Sciences and, in 1997, a full member. In 1995 he was awarded the
Lyapounov prize of the Russian Academy of Sciences, and in 2001 a State
prize from the Russian Federation (for the cycle of works "Differential
equations with meromorphic coefficients"). Besides his scientific work,
in the last period of his life Bolibruch turned out to be a prominent
organizer. From 1996 he was a Deputy Director of the Steklov Mathematical
Institute, then (retaining this position) he became the head of the
mathematical subdivision of the Division of Mathematical Sciences of the
Russian Academy of Science, Vice-chairman of the Moscow Mathematical
Society, and a member of the Scientific Council of the International
Banach Mathematical Center. In 2002 he was elected a member of the
Executive Committee of the IMU. In 2003 he was awarded the prize of the
Charity foundation for the promotion of the native natural and humanitary
sciences, nomination "Prominent scientists". It is difficult to
overestimate his role in the organization of scientific work in Russia
and international collaboration in mathematics.
He participated at many international conferences, often as an invited
plenary lecturer, and he always used the opportunity to meet his western
colleagues and broaden the international connections concerning not only
the fields where he worked himself, but other fields as well. His position,
organizing capabilities, and experience allowed him to play an important
role in organizing international conferences in Russia.
Besides mathematics, Bolibruch had other interests: literature, painting,
theater. It is difficult to convey the warmth of his personality, which
earned him many friends all over the world. He was married and had two
children, a son and a daughter. He was a loving and devoted husband and
father.
Being seriously ill and knowing that there was no guarantee of recovery
(although hoping that the possibility was not excluded), he was still
trying to play a useful role. He was working on his last mathematical
paper, taking part in the supervision of the Steklov Institute and other
organizations, writing memoirs on his life, and advising his students.
His death is a terrible shock, not only to his relatives but to his
friends in many countries. It is a great loss for mathematics and for
Russia.

#### 4. PERSONAL HOME PAGES AND AN ELECTRONIC VERSION OF THE
WORLD DIRECTORY OF MATHEMATICIANS (EWDM): A SUGGESTION OF THE CEIC

After the discontinuation of the WDM was announced in IMU-Net 1 a
number of colleagues asked whether it would be possible to establish
an electronic version of WDM. The IMU Committee on Electronic Information
and Communication (CEIC, see http://www.ceic.math.ca) has attended to
this request and investigated the possibilities.
Due to the limited financial means of the IMU there is no way to set up
and maintain a central registry such as the combined membership list of
AMS/MAA/SIAM/etc., see
http://www.ams.org/cml
It seems feasible, though, to keep a central list - based on distributed
input and voluntary contributions. CEIC proposes to give this idea a try
and start with a basic version of an Electronic World Directory of
Mathematicians (EWDM).
The CEIC would like to couple this suggestion with the request to every
mathematician to offer a personal homepage on the Web. With respect to
the contents and structure of such a personal homepage CEIC proposes the
design of a standardized personal homepage for mathematicians, to be
called the Mathematician's Professional Homepage (MPH), that contains
personal mathematical information in an organized fashion - just as the
Math-Net Page is designed to display institutional mathematical
information in a structured way. The design comes in two versions, a
simple design and a more elaborate one.
The plea to offer and maintain a structured personal webpage should not
be interpreted as a bureaucratic dampening of individual style. Reasons
why structured webpages are desirable can be found at
http://www.mathunion.org/MPH-EWDM
The Personal Homepage Call
IMU asks every mathematician to set up and maintain a personal homepage.
IMU requests that this homepage is presented in a userfriendly way, and
suggests a structure along the lines of the Mathematician's Professional
Homepage (MPH).
The Electronic World Directory of Mathematicians Call
IMU plans to set up and maintain an Electronic World Directory of
Mathematicians (EWDM). Every mathematician who has a homepage is asked to
register the homepage through the EWDM registration mechanism, see
http://www.mathunion.org/ewdm/join.php

Please follow these calls!

#### 5. MATHEMATICS JOURNALS PRICES

Ulf Rehmann from Bielefeld (Germany) writes:
We have a paradoxical situation: It has never been so cheap, easy and
convenient to publish mathematics as it is today, thanks to the Internet,
TeX, and computers, but mathematics publications have never been more
expensive than today. Mathematics departments suffer, because they cannot
afford to buy the journals they used to buy.
If you are concerned with the everlasting question concerning mathematics
journals and their pricings, you might find it helpful to look at the
following tables:
http://www.mathematik.uni-bielefeld.de/~rehmann/BIB/AMS/Publisher.html
These journal price tables reflect the prices for 276 mathematics
journals including their changes during the last 9 years. The tables
have been compiled from information that was collected directly from the
journal publishers by the American Mathematical Society. In order to
make price changes more transparent, the tables have been evaluated and
ordered under certain headings such as changes of the price per volume,
the price per page etc. Some of these changes are stunning.
Ulf Rehmann (Bielefeld, Germany).
PS: My personal opinion on what should be done about the journal price
problems is to be found here:

#### 6. WORLD YEAR OF PHYSICS 2005

For nearly two years, the European Physical Society (EPS) has been
engaged in making 2005 the World Year of Physics (WYP), getting support
of international organisations for its realisation and success. This
initiative was endorsed by the council of EPS and its member societies
in 2001. It is also backed by UNESCO.
The main purpose of the WYP is to raise world-wide public awareness of
physics and, more generally, of physical sciences.
The perception of physics and its importance in our daily life has
decreased in the eyes of the general public to such a low level that the
number of physics students in high schools and universities has
dramatically declined over the past few years. In order to address this
problem, it is important that Physics Societies all over the world become
more active in sharing their visions and convictions about physics with
politicians and the public in general. The illustration of physics,
physical sciences, and their achievements, must be a major axis of the
WYP, and should be the object of numerous and multiform activities aimed
at raising the interest of the general public: radio and television
programmes, articles in newspapers and specialised magazines, books,
action in schools and universities, general colloquia on physical
sciences and the physical view of the world, local and itinerant
exhibits, action in the street, posters, stamps, advertising in mass
transport systems, etc.
Some joint actions between physicists and mathematicians are already
planned for this World Year.

#### 7. SUBSCRIBING TO IMU-NET

IMU is as much concerned about the current wave of spam mails as probably
everybody receiving this email. The current mailing list, called
"IMU-Net-initial", has been carefully selected from various sources including,
e.g.,
the e-mail addresses of those mathematicians who have participated in ICM 2002
in Beijing or ICM 1998 in Berlin. IMU thus hopes that most recipients have
some interest in the issues presented in this electronic newsletter.
Here is IMU's promise concerning the initial list of e-mail addresses:
IMU will send everybody on the current mailing list IMU-Net-initial the first
two issues of IMU-Net. This list will be made inactive at the end of 2003 and
will be replaced by a new IMU-Net mailing list. To get on this list you have
to actively subscribe to the list. Thus, if you want to receive this mail
service in the future, you have to subscribe (no cost involved, of course).
There are two ways of subscribing to IMU-Net:
- Click on http://www.mathunion.org/IMU-Net with a Web browser and go to
the "Subscribe" button to subscribe to IMU-Net online.
- Send an e-mail to imu-net-request@mathunion.org with the Subject-line:
Subject: subscribe

In both cases you will get an e-mail to confirm your subscription so that
misuse will be minimized.
