DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BilTop/68/">
 Partial group cohomology</a>\nby Victor Torres Castillo as part of Bilkent
  Topology Seminar\n\nLecture held in SB-Z11.\n\nAbstract\nPartial groups w
 ere introduced by Chermak as a tool to approach the issue of the existence
  and uniqueness of a centric linking system for a saturated fusion system.
  Roughly speaking\, a partial group is a set with a partially defined prod
 uct (you can still multiply certain strings of elements together\, but not
  always).\nIn this talk\, we will discuss the main similarities and differ
 ences between the categories of partial groups and (actual) groups. Then\,
  we will introduce the cohomology of a partial group inspired by the Gabri
 el-Zisman cohomology\, as defined by Galvez-Neumann-Tonks.\nThe talk is ba
 sed on a joint work in progress with Cihan Okay and Igor Sikora.\n
