DESCRIPTION:Speaker: Pierre-Henri Chaudouard\nhosted by Tamas Hausel\nAbstr
 act: The Arthur-Selberg trace formula is a central tool in the field of au
 tomorphic forms. An open question is to understand or compute its unipoten
 t contribution. For function fields\, this question is among others relate
 d to the counting of Higgs bundles which has a conjectural expression (Hau
 sel-Rodriguez-Villegas-Mozgovoy). In this talk\, in the case of number fie
 lds:\n-- we will give a (refined) conjectural expression à la Hausel-Rodr
 iguez-Villegas for the unipotent part of the Arthur-Selberg trace formula 
 for a "basic test function".\n-- inspired by a work of Schiffmann on Higgs
  bundles\, we will give an expression for this unipotent contribution for 
 a large class of test functions.\n
