Limits of conjugacy classes under iterates of Hyperbolic elements of $\mathsf{Out(\mathbb{F})}$
Abstract
For a free group of finite rank such that , we prove that the set of weak limits of a conjugacy class in under iterates of some hyperbolic is equal to the collection of generic leaves and singular lines of . As an application we describe the ending lamination set for a hyperbolic extension of by a hyperbolic subgroup of in a new way and use it to prove results about Cannon-Thurston maps for such extensions. We also use it to derive conditions for quasiconvexity of finitely generated, infinite index subgroups of in the extension group. These results generalize similar results obtained by Mahan Mj, Kapovich-Lustig and use different techniques.
