Modules whose minimal free resolutions are self-dual or eventually periodic

Commutative Algebra 2025-12-30 v1

Abstract

Let RR be a commutative noetherian local ring. In this paper, we study the self-duality and eventual periodicity of minimal free resolutions of finitely generated RR-modules in terms of their syzygy modules and Ext modules. As an application, we recover theorems of Dey.
