Infinite homotopy stable class for 4-manifolds with boundary

Geometric Topology 2023-11-08 v2

Abstract

We show that for every odd prime qq, there exists an infinite family {Mi}i=1\{M_i\}_{i=1}^{\infty} of topological 4-manifolds that are all stably homeomorphic to one another, all the manifolds MiM_i have isometric rank one equivariant intersection pairings and boundary L(2q, 1) # (S^1 \times S^2), but they are pairwise not homotopy equivalent via any homotopy equivalence that restricts to a homotopy equivalence of the boundary.

Comments

v1: 12 pages. v2: 26 pages. The paper underwent a significant rewrite to account for a gap on page 3 of v1, related to whether the union of two spin manifolds is again spin. The main result of the paper is unaffected
