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

Abstract

In 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.
