Homological properties of simple modules over Leavitt path algebras

Rings and Algebras 2026-05-22 v2

Abstract

Let KK be any field, and let EE be any graph. We explicitly construct the projective resolution of simple left modules over the Leavitt path algebra LK(E)L_K(E) associated to cycles and irreducible polynomials. Then we study the dimension of the KK-vector space of the extensions between two such simple modules.
