Title: Cambrian combinatorics on quiver representations
Abstract: First, we will discuss a polygon model of the Auslander--Reiten quiver of a type A quiver. Next, we will introduce a Catalan object which we call a maximal almost rigid representation. Finally, we will define a partial order on the set of maximal almost rigid representations and show that this partial order is a Tamari or Cambrian lattice. This talk is based on joint work with Emily Barnard, Emily Meehan, and Ralf Schiffler.
