要：I will talk about the problem of studying the reduction modulo p of crystalline representations of dimension 2 of the Galois group of Q_p. In particular, I will be interested in the following situation: fix Hodge-Tate weights and a residual representation, and consider the locus parametrizing crystalline representations with the given weights and reduction modulo p. What can be said about this locus in general?
