Reineke's stable-weight-system conjecture for Dynkin quivers

About 7 years old · traced to

Let QQ be a quiver of Dynkin type. A weight system Θ\Theta on QQ is understood in the sense of stability for representations of QQ, and a representation is stable with respect to Θ\Theta when it satisfies the corresponding stability condition. Reineke's conjecture. There exists a weight system Θ\Theta on QQ such that the stable representations are precisely the indecomposable ones. This conjecture has been proved for quivers of AnA_n-type, whereas computer-found counterexamples exist for quivers of DD- and EE-type; thus the original conjecture is refuted in general. It has applications to stratifications of representation varieties and identities involving quantum dilogarithm series.
