MATH Seminar: “Homology Decompositions for Classifying Spaces of Finite Groups and Linking Systems,” Ergün Yalçın, SA-141, 1:40PM September 30 (EN)

Dear Colleagues and Students,

You are cordially invited to the Topology Seminar organized by the Department of Mathematics.

Speaker: Ergün Yalçın (Bilkent)

“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.
