A geometric model for syzygies over 2-Calabi-Yau tilted algebras II
Ralf Schiffler, Khrystyna Serhiyenko
In this article, we continue the study of a certain family of 2-Calabi-Yau tilted algebras, called dimer tree algebras. The terminology comes from the fact that these algebras can…

A geometric model for syzygies over 2-Calabi-Yau tilted algebras
Ralf Schiffler, Khrystyna Serhiyenko
In this article, we consider the class of 2-Calabi-Yau tilted algebras that are defined by a quiver with potential whose dual graph is a tree. We call these algebras \emph{dimer tr…

Triangulations, order polytopes, and generalized snake posets
Matias von Bell, Benjamin Braun, Derek Hanely +4
This work regards the order polytopes arising from the class of generalized snake posets and their posets of meet-irreducible elements. Among generalized snake posets of the same r…
