time consuming typing or translating work.
Agenda and announcements

Honorary doctorate for Professor Murre
At October 2, 2002, Prof.dr. J.P. Murre received an honorary doctorate from the university of Turin. At this occasion also three other mathematicians
were awarded an honorary doctorate: H.C. Clemens (Ohio State University),
V.A. Iskovskikh (Steklov Mathematical Institute, Moscow) and S. Mori
(RIMS Kyoto University; winner of the Fields Medal in 1990).
The presentation of the honorary doctorates was part of a commemoration
of the wellknown Italian algebraic geometer
Gino Fano (18711952),
who worked at the university of Turin.
From September 29October 5, there was a "Fano conference", with about
50 participants, at which the advances resulting from Fano's work
were discussed.
