Global dimensions of local geodesic ghor algebras

Rings and Algebras 2024-12-09 v1

Abstract

A ghor algebra is a path algebra with relations of a dimer quiver in a compact surface. We show that the global dimension of any cyclic localization of a geodesic ghor algebra on a genus g1g \geq 1 surface is bounded above by 2g+12g+1.This number coincides with the Krull dimension of the center of the ghor algebra. We further show that the bound is an equality if and only if the point of localization sits over the noetherian locus of the center.
