Title:  Growth rate classification for cluster algebras

Abstract:   The growth rate function of a cluster algebra counts the number of cluster variables that can be obtained from the initial cluster in a given number of steps. We classify cluster algebras according to whether their growth rate is bounded, polynomial, or exponential. In particular, we show that all exceptional non-affine mutation-finite cluster algebras have exponential growth.

This is joint work with A. Felikson, H. Thomas, and P. Tumarkin.
