Graph and depth of a monomial squarefree ideal
arXiv:1104.5596
Abstract
Let be a monomial squarefree ideal of a polynomial ring over a field such that the sum of every three different of its minimal prime ideals is the maximal ideal of , or more general a constant ideal. We associate to a graph on , $s=|\Min S/I|$ on which we may {\em read} the depth of . In particular, $\depth_S\ I$ does not depend of char . Also we show that satisfies the Stanley's Conjecture.
