Autumn Kent (Wisconsin Math) On word hyperbolic surface bundles. Abstract: There is a characterization of hyperbolicity of the fundamental group of a surface bundle due to FarbMosherHamenstaedt, namely that the bundle has hyperbolic fundamental group if and only if the fundamental group is ``convex cocompact,'' a notion analogous to the synonymous notion in Kleinian groups. I will discuss joint work with Bestvina, Bromberg, and Leininger that gives a new characterization of convex cocompactness, namely that the group is purely pseudoAnosov and undistorted in the mapping class group.
