On Virtually Cohen-Macaulay Simplicial Complexes

Commutative Algebra 2020-07-21 v1 Combinatorics

Abstract

We examine virtual resolutions of Stanley-Reisner ideals for a product of projective spaces. In particular, we provide sufficient conditions for a simplicial complex to be virtually Cohen-Macaulay (to have a virtual resolution with length equal to its codimension). We also show that all balanced simplicial complexes are virtually Cohen-Macaulay.
