Abstract

We study the irreducible constituents of the reduction modulo p of irreducible algebraic representations V of the group Res K / ℚ p GL 2 for K a finite extension of ℚ p . We show that asymptotically, the multiplicity of each constituent depends only on the dimension of V and the central character of its reduction modulo p . As an application, we compute the asymptotic value of multiplicities that are the object of the Breuil-Mézard conjecture.
