Infinite homotopy stable class for 4-manifolds with boundary

Anthony Conway, Diarmuid Crowley and Mark Powell

Vol. 325 (2023), No. 2, 209–237

We show that for every odd prime q, there exists an infinite family {Mi}i=1 of topological 4-manifolds that are all stably homeomorphic to one another, all the manifolds Mi have isometric rank one equivariant intersection pairings and boundary L(2q,1)#(S1 × S2), but they are pairwise not homotopy equivalent via any homotopy equivalence that restricts to a homotopy equivalence of the boundary.
