Algebra and Combinatorics Seminar: Greg Muller, University of Oklahoma, Friezes of Dynkin type
A "frieze" is an infinite strip of numbers satisfying certain determinantal identities, or any one of several generalizations of this idea. In this talk, I will give an introduction to friezes whose shape is determined by a Dynkin diagram (motivated by their exceptional properties as well as connections to representation theory and cluster algebras).
