Résumé: 
Géométrie Arithmétique et Motivique  Sarithmetic (co)homology and padic automorphic forms  
Description: 
Guillem TarrachIn the last few decades, the theory of padic modular forms has seen many applications to different problems in number theory. This theory is wellunderstood, its central objects of study being overconvergent padic modular forms. However, when attempting to generalize the theory to automorphic forms for more general reductive groups, the picture is less clear. For example, there are several different proposed definitions for spaces of padic automorphic forms, such as overconvergent and completed cohomology. In this talk I will give an overview of the subject and discuss a different proposal, based on the study of the (co)homology of parithmetic groups with coefficients in padic locally analytic representations.
