$\mathbb{CP}^2$-stable classification of $4$-manifolds with finite fundamental group

Geometric Topology 2021-03-10 v2

Abstract

We show that two closed, connected 44-manifolds with finite fundamental groups are CP2\mathbb{CP}^2-stably homeomorphic if and only if their quadratic 22-types are stably isomorphic and their Kirby-Siebenmann invariant agrees.
