Bounding the Dehn surgery number by 10/8

Geometric Topology 2024-05-28 v1

Abstract

We provide new examples of 3-manifolds with weight one fundamental group and the same integral homology as the lens space L(2k,1)L(2k,1) which are not surgery on any knot in the three-sphere. Our argument uses Furuta's 10/8-theorem, and is simple and combinatorial to apply.
