Pretty much any of these will directly translate over the Alexander duality barrier to a criterion for D(C) to be a matroid. I'll mention that a specific place where the situation you mention has arisen is in the paper of Eagon and Reiner "Resolutions of Stanley-Reisner rings and Alexander duality". | |
