The Mathematical Institute Newsletter is maintained
by Jan-Hendrik Evertse.
The newsletter is issued the first week of each
month, except for July and August.
The electronic version of the newsletter can be found on
(go to the homepage of the Mathematical Institute and click on "Newsletter").
Copy for the May newsletter, such as announcements, personal
notes, visits to conferences, guests (with
place of origin and date of arrival and departure),
lectures of general
interest, Ph.D. thesis defenses (with title of thesis), etc.
should be sent by e-mail to
evertse at math.leidenuniv.nl
before April 27.
Copy should be submitted in English plaintext,
so that it can be inserted into the newsletter
without time consuming typing or translating work.

Abel Prize 2004 awarded to Atiyah and Singer
(Copied from the electronic IMU newsletter, March 2004)
The Norwegian Academy of Science and Letters has decided to award
the Abel Prize for 2004, jointly to Sir Michael Francis Atiyah,
University of Edinburgh (UK) and Isadore M. Singer, Massachusetts
Institute of Technology (USA).
Atiyah and Singer will receive the prize "for their discovery and
proof of the index theorem, bringing together topology, geometry and
analysis, and their outstanding role in building new bridges between
mathematics and theoretical physics".
The Abel Prize Award ceremony will take place 25 May 2004 at the
University of Oslo Aula.
The Abel Prize, established by the Norwegian Goverment in 2002 and
awarded annually, is an international prize for outstanding
scientific work in the field of mathematics. The Prize carries a
cash award of 6 million Norwegian kroner (about US $ 800,000).
