REPRESENTATION
THEORY AND RELATED TOPICS SEMINAR
ABSTRACT: Associated
permutations were already used when Fomin-Zelevinsky first defined
cluster algebras. They are also naturally defined for reddening
sequences and in particular maximal green sequences. We have defined
several new concepts to extend the definition of associated
permutations to arbitrary mutation sequences albeitly with the
permutations no longer being canonical in most cases. In this talk I
will explain these new concepts and their applications to cluster
algebras. If time permits I will also talk about other results about
the associated permutations.
