Regular points in system spaces. (Q1874301)

The authors characterize the regular points in system spaces using representation theory of quivers. They start with indecomposable representations and roots. For roots cases they deal with Schur representations and Schur roots. Then they give the characterization of regular points in system spaces. Moreover, they describe all prestable points (special regular points) in system spaces and introduce another generic property on the decompositions of dimensional vectors.
