“Homology decompositions for classifying spaces of finite groups and linking systems”
Abstract: This will be a series of two talks. The aim is to understand the homology decompositions for linking systems. In this first talk, I will briefly explain the three types of mod-p homology decompositions for classifying space of a finite group, namely the subgroup, centralizer, and normalizer decompositions. I will show how the sharpness of the subgroup decomposition over nontrivial p-subroups is proved.
The sharpness of the subgroup decomposition for linking systems is an important open problem in this area.
