A Numerical Characterization of Gorenstein Complexes
Let V be a finite set, called the vertex set, and let .1 be a simplicial complex on V. Thus .1 is a collection of subsets of V such that (i) {x} EL1 for any x E V, and (ii) a E .1, 'r c a imply 'r E L1. An element a of .1 is called an i-face if #( a) = i + 1. Here, #( a) is the cardinality of a as a set. The positive integer dim .1: = max{ #( a) 1; a E L1} is called the dimension of .1. Let v =...

Let $(R, m)$ be a commutative noetherian local ring and let $Gamma$ be a finite group. It is proved that if $R$ admits a dualizing module, then the group ring $Rga$ has a dualizing bimodule as well. Moreover, it is shown that a finitely generated $Rga$-module $M$ has generalized Gorenstein dimension zero if and only if it has generalized Gorenstein dimension zero as an $R$-module.
متن کاملIntersection Multiplicities over Gorenstein Rings
LetR be a complete local ring of dimension d over a perfect field of prime characteristic p, and let M be an R-module of finite length and finite projective dimension. S. Dutta showed that the equality limn→∞ `(F n R(M)) pnd = `(M) holds when the ring R is a complete intersection or a Gorenstein ring of dimension at most 3. We construct a module over a Gorenstein ring R of dimension five for wh...
