# Workshop on Galois Representations and Automorphic Forms

The workshop will combine background talks aimed at graduate students and post-docs with research reports on the latest developments. The list of speakers will be decided nearer the date of the workshop so as to be able to incorporate last minute devleopments. The workshop will concentrate on the following topics:

Automorphy and potential automorphy of Galois representations and applications.

Integral models of cohomology of Shimura varieties and Rapoport-Zink spaces.

p-adic comparison theorems and applications to modular/automorphic forms.

p-adic L-functions and main conjectures, especially methods coming from automorphic forms.

## Organizers:

Pierre Colmez, National Center for Scientific Research/IAS, Michael Harris, University of Paris VII/IAS, Christopher Skinner, Princeton University/IAS, Richard Taylor, Harvard University/IAS

## Speakers:

D. Burns (King's College London), F. Calegari (IAS), Ana Caraiani (Harvard), L. Clozel (U Paris), G. Dospinescu (Ecole Polytechnique), T. Gee (IAS), D. Geraghty (IAS), M. Emerton (Northwestern), H. Hida (UCLA), A. Iovita (Concordia), M. Kakde (Univ College London), T. Kaletha (IAS), S. Morel (IAS), V. Paskunas (Univ Bielefeld), V. Pilloni (Columbia), P. Scholze (Univ Bonn), M-F. Vigneras (Univ Jussieu) and J. Weinstein (IAS)

## Participants:

The following people will be in attendance for most, if not all, of the workshop activities: L. Berger, F. Diamond, T. Haines, M. Harris, F. Herzig, C. Khare, K.-W. Lan, T. Liu, E. Mantovan, J. Newton, S. W. Shin, C. Skinner, J. Suh, R. Taylor, Y. Tian, E. Urban, A. Wiles.

Registration for the meals and workshop is reqired. (Speakers do not need to register.)

Although there is no registration fee, because seating is limited both in the seminar room and in our dining hall, you are requested to register if you wish to attend all or part of the workshop. In addition, in order for our chef to prepare enough food, we need to have a headcount for the meals. Please note the workshop attendees are expected to pay for their lunch. Approximate range of prices is $4.00 for a salad to$9.00 for an entree. Vegetarian lunches will be available. Only cash is accepted at the cash registers. Credit cards and personal checks are not accepted.
