Congruences (mod p) for PEL type modular forms
Abstract: I will discuss congruences modulo a prime p between modular forms arising
from geometric (PEL) and algebraic settings. In particular I will explain
how, by allowing changes in the weights, the (mod p) Hecke eigenforms
associated to some reductive groups G can be seen as eigenforms associated
to an inner form of G which is compact modulo center at the infinite
places. This type of considerations were originally made by J-P. Serre for
elliptic modular forms.
