Admissible Dissections of Surfaces and Piano Algebras
Admissible dissections of marked surfaces were used to classify gentle algebras and to provide a geometric model for their derived categories by Opper-Plamondon-Schroll. We introduce the notion of an extended admissible dissection of a marked surface, and the piano algebra associated to an extended admissible dissection. We will discuss how the set of extended admissible diagrams of a marked disc …

On a class of quasi-hereditary algebras arising from Reedy categories
The natural numbers and the weakly monotone functions between them form a category, called the cosimplicial indexing category, which is fundamental in the theory of simplicial sets. A Reedy category is a certain generalization, heavily used in homotopy theory. In this talk, we focus on Reedy categories having finitely many objects (any truncation of the cosimplicial indexing category is an …
