Mutation of type $D$ friezes

A. Garcia Elsener, K. Serhiyenko

Published 2019-04-26Version 1

In this article we study mutation of friezes of type $D$. 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 $D$ frieze into a sub pattern of a frieze of type $A$ and the mutation formula for type $A$ friezes recently found by Baur et al.
