Minimal Euler Characteristics for Even-Dimensional Manifolds with A Given Fundamental Group
Ponente(s): Alejandro Adem .
In this talk we will discuss estimates for the minimal Euler characteristic of even
dimensional manifolds with a given fundamental group and a highly connected universal
cover. As an application we obtain new restrictions for non-abelian finite groups arising as
fundamental groups of rational homology 4–spheres. This is joint work with Ian
