Stratifying systems over the hereditary path algebra with quiver ${\mathbb{A}}_{p,q}$

Paula Andrea Cadavid, Eduardo do Nascimento Marcos

The authors have proved in [J. Algebra Appl. 14 (2015), no. 6] that the size of a stratifying system over a finite-dimensional hereditary path algebra $A$ is at most $n$, where $n$…
