Abstract:
Noetherian quivers have been studied and characterized (when the number of arrows is finite) by Höinghuas and Richter in [10]. In this paper we give a characterization of noetherian quivers in the most general case in Theorem 3.6. We prove that a quiver is noetherian if and only if the rooted tree associated to any vertex satisfies some sort of finiteness condition, if and only if every finitely generated representation over a noetherian ring has an injective cover.
