Seminar February 15 – Johanna Mangahas Kutluhan

Our Spring 2011 seminar continued on Feb. 15th with Johanna Mangahas Kutluhan from Brown University.

Title: Geometry of right-angled Artin groups in mapping class groups

Abstract: I’ll describe joint work with Matt Clay and Chris Leininger. We give sufficient conditions for a finite set of mapping classes to generate a right-angled Artin group. This subgroup is quasi-isometrically embedded in the whole mapping class group, as well as, via the orbit map, in Teichmueller space with either of the standard metrics. Subsurface projection features prominently in the proofs.
