Maximal depth property of finitely generated modules

Commutative Algebra 2018-02-22 v1

Abstract

Let (R,m)(R,\mathfrak{m}) be a Noetherian local ring and MM a finitely generated RR-module. We say MM has maximal depth if there is an associated prime p\mathfrak{p} of MM such that depth M=dimR/pM=\dim R/\mathfrak{p}. In this paper, we study finitely generated modules with maximal depth. It is shown that the maximal depth property is preserved under some important module operations. Generalized Cohen--Macaulay modules with maximal depth are classified. Finally, the attached primes of Hmi(M)H^i_{\mathfrak{m}}(M) are considered for i<dimMi<\mathrm{dim} M.
