Some Schottky subgroups of mapping class groups
Johanna Mangahas Kutluhan (Brown)
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. 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. 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.
