Cohomologie cuspidale des champs de Chtoucas / Cuspidal cohomology of stacks of Shtukas

Xue, Cong 07 June 2017 (has links)
Dans cette thèse, on construit le morphisme terme constant pour les groupes de cohomologie l-adique à supports compacts des champs classifiants des G-Chtoucas. Ensuite on définit la partie cuspidale de ces groupes de cohomologie et on montre qu'elle est de dimension finie. De plus, on montre que la partie cuspidale coïncide avec la partie Hecke-finie au sens rationnel. / In this thesis, we construct the constant term morphism for the l-adic cohomology groups with compact supports of the classifying stacks of the G-Shtukas. Then we define the cuspidal part of these cohomology groups and we prove that it is of finite dimension. Moreover, we show that the cuspidal part coincides with the Hecke-finite part in the rational sense.
