RAAGs in MCGs

Abstract: We give a new proof of a theorem of Koberda which says that right-angled Artin subgroups of mapping class groups abound. This alternative approach uses the hierarchical structure of the curve complex, which allows for more explicit computations. Time permitting, we will also discuss some applications to the theory of convex cocompactness in mapping class groups.
