Title: Some Schottky subgroups of mapping class groups
Abstract: Farb and Mosher defined a notion of "convex cocompact" for subgroups of mapping class groups that models the original definition of convex cocompact for Kleinian groups; free groups of either kind are called Schottky. Â I'll describe a way to construct examples of Schottky mapping class subgroups that is (at least, a priori), different from the original "abundant" examples Farb and Mosher described. Â These examples grow out of one way, described by Clay, Leininger, and myself, to quasi-isometrically embed free groups (and more generally, right-angled Artin groups) into mapping class groups.
