Filtrations of Totally Reflexive Modules

Abstract

In this paper, we will introduce a subcategory of totally reflexive modules that have a saturated filtration by other totally reflexive modules. We will prove these are precisely the totally reflexive modules with an upper-triangular presentation matrix. We conclude with an investigation of the ranks of Ext1\operatorname{Ext}^1 of two such modules over a specific ring.
