A remark on the constructibility of real root representations of quivers using universal extension functors

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/165199In this paper we consider the following question: Is it possible to construct all real root representations of a given quiver Q by using universal extension functors, starting with a real Schur representation? We give a concrete example answering this question negatively.8 pages, shorter than older verisonRepresentation TheoryRings and Algebras16G20A remark on the constructibility of real root representations of quivers using universal extension functorstext
