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