$F$-stable submodules of top local cohomology modules of Gorenstein rings

Commutative Algebra 2007-05-23 v1

Abstract

This paper applies G. Lyubeznik's notion of FF-finite modules to describe in a very down-to-earth manner certain annihilator submodules of some top local cohomology modules over Gorenstein rings. As a consequence we obtain an explicit description of the test ideal of Gorenstein rings in terms of ideals in a regular ring.
