BEST WISHES FOR 2004
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 February newsletter, such as announcements, personal notes, visits to conferences, guests (with 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 January 27. Copy should be submitted in English plaintext, so that it can be inserted into the newsletter without time consuming typing or translating work.
