Conference on Galois Representations and Automorphic Forms

I am a co-organizer of a Conference on Galois Representations and Automorphic Forms which will take place in the Banach Center in Bedlewo (Poland), near Poznan. If you are interested in attending or would like more information about the conference, please, email me or one of the other organizers.
