Abstract

In this paper, we prove a higher dimensional version of Auslander-Iyama-Solberg correspondence. Iyama and Solberg have shown a bijection between nn-minimal Auslander-Gorenstein algebras and nn-precluster tilting modules. If AA is an nn-minimal Auslander-Gorenstein algebra, then the pair (A,P)(A,P) is a relative (n+1)(n+1)-Auslander-Gorenstein pair in the sense of the authors, where PP is the minimal faithful projective-injective left AA-module. We establish a higher dimensional Auslander-Iyama-Solberg, where PP is replaced by any self-orthogonal module QQ having finite projective and injective dimension. This new correspondence provides a bijection between relative Auslander--Gorenstein pairs and a new class of objects that generalise precluster tilting modules. This way, we obtain a new correspondence coming from the modular representation theory of general linear groups.
