ACTIVITIES

WORKSHOP 29/30 june
"On p-adic representations for Galois groups of fields with non-perfect residue field "
The aim is to deal with recent progress on the subject: both with application to p-adic differential equations and with Fontaine relative theory.
The lectures will have a very "colloquial stile": hence they can be longer than usual (i.e. without defined ends...)
Room: 1BC45

Friday 29, 11.30-....
-Olivier Brinon (Paris XIII): Sen theory for $B_{DR}$ representations in relative case

Friday 29, 15.30-....
-Bruno Chiarellotto( Padova): From representations to p-adic differential equations: the non perfect residual case

Saturday 30, 10.00-....
-Fabrizio Andreatta (Milan): On $(phi, gamma)$-relative modules.

Saturday 30, 14.00-...
-Andrea Pulita (Bielefeld) On the arithmetic and differential Swan conductors for rank one representations for non perfect residue fields.

Final conference of the EU network "Arithmetic Algebraic Geometry".
In Cetraro from 7 october to 13 october.
Sponsored by EU and Japan Math. Society.
-Scientific commitee
M. Bertolini (Milan), B. Chiarellotto (Padova), S. Bosch (Muenster), M. Rapoport (Bonn), A.J. Scholl (Cambridge).
