Title: Leonard pairs, spin models, and distance-regular graphs

Speaker: Paul Terwilliger Affiliation: University of Wisconsin Zoom: Contact Soffia Arnadottir

Abstract:

A Leonard pair is an ordered pair of diagonalizable linear maps on a finite-dimensional vector space, that each act on an eigenbasis for the other one in an irreducible tridiagonal fashion. In this talk we consider a type of Leonard pair, said to have spin.
