(go to the homepage of the Mathematical Institute and click on "Newsletter").
Copy for the October newsletter, such as announcements, personal
notes, visits to conferences, guests, lectures of general
interest, Ph.D.defenses,
or other announcements of general interest should be sent
by email to
evertse@math.leidenuniv.nl
before September 27.
Copy should be submitted
in English plaintext,
so that it can be inserted into the newsletter without time consuming typing
or translating work.

EIDMAStieltjes Onderwijsweek/Graduate
Course on Cryptography from September 2226
From September 2226 there is a course on
cryptography at the Lorentz Center which is meant for graduate
and advanced undergraduate students in mathematics,
and anybody else interested.
This course is meant as a preparation for the workshop
Mathematics of Cryptology the week thereafter.
On September 26 there is an overlap between this graduate course
and the workshop,
with lectures for a nonspecialized audience.
The course
is coordinated by Ronald Cramer (BRICS, Aarhus, Denmark),
Bas Edixhoven (University of Leiden) and Berry Schoenmakers
(Technical University of Eindhoven).
