Title: Representation stability for diagram algebras
Abstract: Diagram algebras like the TemperleyLieb algebra, Brauer algebra, and partition algebra are easy to explain by pictures and come up in various settings as SchurWeyl duality, statistical mechanics, or knot theory. They have many similarities to the group algebra of the symmetric group, in particular, they are often semisimple and their irreducible representations are indexed by partitions. In this talk, I will introduce these algebras and their representation theory, and then explore sequences of representations, define the notion of representation stability for them, and give a categorical criterion for this notion.
