"Fusion
systems and left stable bisets"

By

Abstract: For constructing free actions on products of spheres, one of the
obstructions is the existence of a finite group satisfying certain properties.
In our joint work with Ozgun Unlu,
we constructed these finite groups using fusion systems. The idea is first
finding a suitable left stable biset and then take
this finite group as the group of automorphisms of
this biset. I will explain this method starting from
basic definitions.
