Topological spines of $4$–manifolds

Hee Jung Kim and Daniel Ruberman
Algebraic & Geometric Topology 20 (2020) 3589–3606
DOI: 10.2140/agt.2020.20.3589
Abstract

We show that infinitely many of the simply connected 4–manifolds constructed by Levine and Lidman that do not admit PL spines actually admit topological spines.
