The No Gap Conjecture for tame hereditary algebras
Stephen Hermes, Kiyoshi Igusa
The "No Gap Conjecture" of Brüstle-Dupont-Pérotin states that the set of lengths of maximal green sequences for hereditary algebras over an algebraically closed field has no gaps.…

Semi-invariant pictures and two conjectures on maximal green sequences
Thomas Brüstle, Stephen Hermes, Kiyoshi Igusa +1
We use semi-invariant pictures to prove two conjectures about maximal green sequences. First: if is any acyclic valued quiver with an arrow of infinite type then any m…

Minimal Model of Ginzburg Algebras
Stephen Hermes
We compute the minimal model for Ginzburg algebras associated to acyclic quivers . In particular, we prove that there is a natural grading on the Ginzburg algebra making it form…
