DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GDEq/94/">De
 rivations in group algebra bimodules</a>\nby Andronick Arutyunov as part 
 of Geometry of differential equations seminar\n\nLecture held in room 303 
 of the Independent University of Moscow.\n\nAbstract\nIf one introduces a 
 norm in a group algebra which is understood as a vector space and consider
 s a closure over this norm\, a natural structure of a free bimodule over a
  group ring arises. The most natural example is $\\ell_p(G)$\, for $p \\ge
 q 1$. This structure makes it natural to consider the problem of describin
 g derivations with values in such bimodules\, which I will talk about. A "
 character" approach will be used\, which consists in identifying the deriv
 ations with characters on a suitable category (in our case\, the groupoid 
 of adjoint action of a group on itself)\, and further study is already und
 erway with the active use of combinatorial methods.\n
