Title: Scaffolds

Speaker: William J. Martin Affiliation: Worcester Polytechnic Institute Zoom: Contact Soffia Arnadottir

Abstract:

Building on the work of various authors who have used tensors in the study of association schemes and spin models, I propose the term "scaffold" for certain tensors that have been represented by what are sometimes called "star-triangle diagrams" in the literature. The main goal of the talk is to introduce and motivate these objects which somewhat resemble partition functions as they appear in combinatorics. (The exact definition is too cumbersome to include here.)
