Abstract

A group G is called acylindrically hyperbolic if it admits a non-elementary acylindrical action on a hyperbolic space. It includes many examples of interest, e.g., nonelementary hyperbolic and relatively hyperbolic groups, all but finitely many mapping class groups of punctured closed surfaces, most 3-manifold groups and Out(Fn) for n > 1. Although BS(p, q) is essentially never acylindrically hyperbolic we will see in this talk that Out(BS(p, q)) is acylindrically hyperbolic for non-solvable Baumslag-Solitar groups, and explore further properties of the group using its acylindricity. This is joint work with Daxun Wang.
