-Vectors and Non-Self-Crossing Curves for Acyclic Quivers of Finite Type

Let be an acyclic quiver and k be an algebraically closed field. The indecomposable exceptional modules of the path algebra have been widely studied. The real Schur roots of the root system associated with are the dimension vectors of the indecomposable exceptional modules. It has been shown in [...

description Let be an acyclic quiver and k be an algebraically closed field. The indecomposable exceptional modules of the path algebra have been widely studied. The real Schur roots of the root system associated with are the dimension vectors of the indecomposable exceptional modules. It has been shown in [Nájera Chávez A., Int. Math. Res. Not. 2015 (2015), 1590-1600] that for acyclic quivers, the set of positive -vectors and the set of real Schur roots coincide. To give a diagrammatic description of -vectors, K-H. Lee and K. Lee conjectured that for acyclic quivers, the set of -vectors and the set of roots corresponding to non-self-crossing admissible curves are equivalent as sets [Exp. Math., to appear, arXiv:1703.09113]. In [Adv. Math. 340 (2018), 855-882], A. Felikson and P. Tumarkin proved this conjecture for 2-complete quivers. In this paper, we prove a revised version of the Lee-Lee conjecture for acyclic quivers of type , , and ₆ and ₇.
