Configuration Spaces and Polyhedral Products

Abstract

This paper aims to find the most general combinatorial conditions under which a moment-angle complex $(D^2,S^1{)}^K$ is a co-$H$-space, thus splitting unstably in terms of its full subcomplexes. In this way we study to which extent the conjecture holds that a moment-angle complex over a Golod simplicial complex is a co-$H$-space. Our main tool is a certain generalisation of the theory of labelled configuration spaces.
