Auslander–Reiten conjecture for Auslander-Gorenstein algebras

Let AA be an algebra satisfying the Auslander condition, meaning that it is nn-Gorenstein for every n1n\geq 1. Auslander–Reiten conjecture. If AA satisfies the Auslander condition, then AA is Auslander-Gorenstein. This is the main open homological conjecture related to Auslander-Gorenstein algebras. Auslander and Reiten formulated it as a question; under the same hypotheses, it is equivalent to the question of whether finite finitistic dimension implies being Iwanaga-Gorenstein.
