The Mathematical Institute Newsletter is maintained by Jan-Hendrik Evertse. The newsletter will be 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").

The newsletter of June will cover the months June, July and August. Copy for this newsletter, such as announcements, personal notes, visits to conferences, guests, lectures of general interest, PhD.-defenses or doctoral exams under your supervision, should be sent by e-mail to evertse@math.leidenuniv.nl before May 27. Copy should be submitted in English plaintext, so that it can be inserted into the newsletter without time consuming typing or translating work.


Delft-Leiden Colloquium on Thursday May 8 at the Lorentz Center

In connection with the integration of the mathematics programs of Leiden University and Delft University of Technology, there will be a colloquium at which researchers from Delft and Leiden give short presentations about on-going research. The colloquium is organized by Roger Cooke (Delft) and Bas Edixhoven. The colloquium is on May 8 at the Lorentz Center. Those who are interested to attend this meeting and have not registered yet are urged to fill out the on-line registration form on the website of the Lorentz Center (http://www.lc.leidenuniv.nl, go to program workshops -year 2003 and then to May 8). The lectures will be in Dutch. The program is given below.
