We study the local cohomology modules H k ⌬ of the Stanley᎐Reisner ring w x k ⌬ of a simplicial complex ⌬ with support in the ideal I ; k ⌬ corresponding ⌺ to a subcomplex ⌺ ; ⌬. We give a combinatorial topological formula for the multigraded Hilbert series, and in the case where the ambient comple
A simplicial complex 2 on the vertex set V=[x 1 , x 2 , ..., x v ] is a collection of subsets of V such that (i) Let H i (2; k) denote the ith reduced simplicial homology group of 2 with the coefficient field k. Note that H &1 (2; k)=0 if 2{[<], H &1 ([<]; k)$k, and H i ([<]; k)=0 for each i 0. We
