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