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 http://www.math.leidenuniv.nl/~evertse/newsletter.shtml
(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).
