DESCRIPTION:Speaker: Jack Saunders - University of Birmingham\n\nTitle:
Higher group cohomology and PSL(2\,q)\n\nAbstract: Given a finite group
G acting irreducibly on a vector space V\, the first cohomology group H1
(G\,V) corresponds to conjugacy classes of complements to V in the semid
irect product V \\rtimes G and H2(G\,V) to equivalence classes of group
extensions of G by V. A little is known about the size of H1 in various
cases\, but what about H2 or higher? In this talk\, we give a brief over
view of some bounds for the dimension of cohomology for groups of Lie ty
pe\, along with a new general result and some results about the cohomolo
gy of PSL(2\,q).\n\nTime: 2pm\n\nPlace: Zoom
