Noetherian criteria for dimer algebras

Rings and Algebras 2024-01-02 v3

Abstract

Let AA be a nondegenerate dimer (or ghor) algebra on a torus, and let ZZ be its center. Using cyclic contractions, we show the following are equivalent: AA is noetherian; ZZ is noetherian; AA is a noncommutative crepant resolution; each arrow of AA is contained in a perfect matching whose complement supports a simple module; and the vertex corner rings eiAeie_iAe_i are pairwise isomorphic.
