Abstract

Let (R,m) be a Noetherian local ring, let I be an ideal of R, and let M be a finitely generated R-module with d=dim(M). In this paper, we establish shifted principles under localization and completion for attached primes of the top local cohomology module HId(M). We characterize the catenarity, the weak going-up property, and the strong Lichstenbaum-Hartshorne vanishing property of the base ring R in terms of these shifted principles of the top local cohomology modules.
