Event description: 

Abstract: Following Harman, Snowden and Snyder we’ll explain the construction of the Delannoy category, its properties and how it leads to a categorification of the ring of integer-valued polynomials. We’ll also discuss a diagrammatic description of that category, in a work in progress with Noah Snyder.
