Alejandro Adem, University of British Columbia, “Homotopy group actions and group cohomology”
SAS 4201Let G denote a finite group and X a CW-complex. A homotopy group action is defined as a homotopy class of maps BG -- BAut(X). In this talk we will analyze these actions using techniques from group cohomology. We will show how they relate to geometric actions and how they can be used to construct…
