Abstract:
Let e(G, S) be the exponential growth rate of a finite generated group G with a finite generating set S. Let ξ(G) be the set {e(G, S)} for all finite generating sets S of G. Sela and I proved that if G is a non-elementary hyperbolic group, then ξ(G) is well-ordered. I also plan to discuss the set of growth rates for a family of groups. That is a joint work with Breuillard.
