Mutation of type $D$ friezes

Combinatorics 2020-06-09 v2 Rings and Algebras

Abstract

In this article we study mutation of friezes of type DD. We provide a combinatorial formula for the entries in a frieze after mutation. The two main ingredients in the proof include a certain transformation of a type DD frieze into a sub pattern of a frieze of type AA and the mutation formula for type AA friezes recently found by Baur et al.
