SUMMARY:Extensions of finite groups, group algebras, and decomposition of étale gerbes
DESCRIPTION:Speaker: Hsian-Hua Tseng\, University of Wisconsin-Madison\n\nLet G be a finite group. A G-gerbe over a space X may be intuitively thought of as a fiber bundle over X with fibers being the classifying space (stack) BG. In particular BG itself is the G-gerbe over a point. A more interesting class of examples consist of G-gerbes over BQ, which are equivalent to …
