Seminar Aachen-Köln-Lille-Siegen on Automorphic Forms

In the summer 2003 we, i.e. Jan Bruinier from Köln, Valery Gritsenko from Lille, Aloys Krieg from Aachen and Nils Skoruppa, agreed to start a joint seminar, which should take place four times each year hosted alternately by our home universities, respectively. The original aim was to broaden the platform for our students doing research with us in the field of automorphic forms.

Since then we organized many of these one afternoon workshops with increasing success. Moreover, our seminar gained recognition outside our four universities and usually during our meetings you have the possibility to meet researchers from several other German or French universities or from the Max-Planck institute for Mathematics at Bonn. Accordingly, this seminar is now a platform not only for our students, but, as one may recognize from the names of the speakers, for all researches from the Benelux countries, from Switzerland and Germany and sometimes from outside Europe. The list of all speakers so far, including the posters of the meetings and many snapshots, can be found below.
