Polyhedral products for simplicial complexes with minimal Taylor resolutions

Algebraic Topology 2017-03-20 v2 Combinatorics

Abstract

We prove that for a simplicial complex KK whose Taylor resolution for the Stanley-Reisner ring is minimal, the following four conditions are equivalent: (1) KK satisfies the strong gcd-condition; (2) KK is Golod; (3) the moment-angle complex ZK\mathcal{Z}_K is homotopy equivalent to a wedge of spheres; (4) the decomposition of the suspension of the polyhedral product ZK(CX,X)\mathcal{Z}_K(C\underline{X},\underline{X}) due to Bahri, Bendersky, Cohen, and Gitler desuspends.
