RésumeLet B be a definite quaternion algebra over the rationals, G the algebraic group defined by the units in B and H the subgroup of G of norm one elements. The classical transfer of automorphic representations from G to H is well understood thanks to Labesse and Langlands who proved formulas for the multiplicity of irreducible admissible representations of H(adeles) in the discrete automorphic spectrum. The goal of this talk is to study a p-adic version of this transfer. By this we mean an extension of the classical transfer to p-adic families of automorphic forms as parametrized by eigenvarieties. The aim will be to find a morphism between eigenvarieties, which agrees with the classical transfer on points corresponding to classical automorphic representations.
