DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UAANTS/28/">
 Eisenstein cocycles and values of L-functions</a>\nby Luis Garcia (UCL) as
  part of University of Arizona Algebra and Number Theory Seminar\n\n\nAbst
 ract\nThere are several recent constructions by many authors of Eisenstein
  cocycles of arithmetic groups. I will discuss a point of view on these co
 nstructions using equivariant cohomology and equivariant differential form
 s. The resulting objects behave like theta kernels relating the homology o
 f arithmetic groups to algebraic objects. As an application\, I will expla
 in the proof of some conjectures of Sczech and Colmez on critical values o
 f Hecke L-functions. The talk is based on joint work with Nicolas Bergeron
  and Pierre Charollois.\n
