Abstract

The construction of a simplicial complex given by polyhedral joins (introduced by Anton Ayzenberg), generalizes Bahri, Bendersky, Cohen and Gitler’s $J$-construction and simplicial wedge construction. This article gives a cohomological decomposition of a polyhedral product over a polyhedral join. A formula for the Hilbert–Poincaré series is given, which generalizes Ayzenberg’s formula for the moment-angle complex.

Keywords
