Abstract

Let A ⊆ B be a homogeneous extension of Noetherian standard Nr-graded rings with A0 = B0 = R. Let M be a finitely generated Nr-graded B-module and N ⊆ M a finitely generated graded A-submodule of M. In this paper, we investigate the asymptotic behavior of the set of primes associated to the module Mn / Nn and prove that for all sufficiently large n ∈ Nr, the set AssR (Mn / Nn) is stable. We also give a certain inequality for the spread of standard multigraded rings, which is a natural generalization of Burch's inequality for the analytic spread of an ideal.
