Concordance of $\mathbb{Z}_p\times\mathbb{Z}_p$ actions on $S^4$

Michael McCooey

Algebraic & Geometric Topology 7 (2007) 785–796

arXiv: math.GT/0511212

Abstract

We prove that locally linear, orientation-preserving actions of G = p × p on S4 are concordant if and only if a 2–valued surgery obstruction vanishes, and discuss constructions and examples.

Keywords
