On sign coherence of c-vectors
Abstract
Given a finite dimensional algebra A over an algebraically closed field, we consider the c-vectors such as defined by Fu in Fu2017 and we give a new proof of its sign-coherence. Moreover, we characterise the modules whose dimension vectors are c-vectors as bricks respecting a functorially finiteness condition.
