Learning Seminar 9/15

Speaker: Melissa Sherman-Bennett

Abstract: I'll give a taste of the topics we'll discuss during the rest of the semester, focusing on the example of the torus knot T(n,n+1). The combinatorics that appears includes the q-Catalan numbers, point counts of the open positroid variety in Gr(n,2n+1), and the diagonal coinvariant ring.

Notes for the talk are here.
