Sign-coherence of c-vectors and maximal green sequences for acyclic sign-skew-symmetric matrices
arXiv:2004.04390
Abstract
In this paper we construct an unfolding for vectors of acyclic sign-skew symmetric matrices and we also prove that the sign-coherence property holds for acyclic sign-skew-symmetric matrices. Then we prove that every acyclic sign-skew-symmetric matrix admits a maximal green sequence.
