Auslander–Reiten map characterisation of Auslander-Gorenstein algebras
Auslander–Reiten map characterisation of Auslander-Gorenstein algebras
Let be a finite-dimensional -algebra over an algebraically closed field . Say that has a well-defined Auslander–Reiten map if every indecomposable injective -module has a finite minimal projective resolution whose last term is an indecomposable projective module. Auslander–Reiten map conjecture. The algebra is Auslander-Gorenstein if and only if it has a well-defined Auslander–Reiten map that is a bijection. This conjecture proposes a converse to the Auslander–Reiten bijection for Auslander-Gorenstein algebras and would characterise such algebras through their injective resolutions.
