Next talk: Frieze Patterns Date: Thursday, 19 March 2026, 2:00 - 3:00 pm. Room: 478 Speaker: Deepanshu Prasad Abstract: Frieze patterns, introduced by H. S. M. Coxeter and John Conway, are arrays of numbers satisfying a simple local determinant rule. Despite their elementary definition, they have deep connections with combinatorics, cluster algebras, and representation theory. In this talk, I will briefly review classical frieze patterns and then discuss infinite friezes. I will describe their basic properties and illustrate how they arise naturally in combinatorial and representation-theoretic settings.
