Yiping Chen (Wuhan University), Singular equivalences and the Auslander-Reiten conjecture.

Abstract:
Let k be a field, and A be a finite dimensional k-algebra. The Auslander-Reiten conjecture says that every finitely generated left A-module M satisfying that Extⁿ_A(M, M ⊕ A)=0 for all n>0 must be projective. The Auslander-Reiten conjecture is closely connected with the famous Nakayama conjecture and the finitistic dimension conjecture. In this talk, we will discuss this conjecture under certain singular equivalences, and show that it holds for all skew-gentle algebras.
