Abstract

In this paper, we study a relationship between tilting modules with finite projective dimension and dominant dimension with respect to injective modules as a generalization of results of Crawley-Boevey-Sauter, Nguyen-Reiten-Todorov-Zhu and Pressland-Sauter. Moreover, we give characterizations of almost nn-Auslander-Gorenstein algebras and almost nn-Auslander algebras by the existence of tilting modules. As an application, we describe a sufficient condition for almost 11-Auslander algebras to be strongly quasi-hereditary by comparing such tilting modules and characteristic tilting modules.
