Extensions of Veech groups II: Hierarchical hyperbolicity and quasi-isometric rigidity
arXiv:2111.00685 · doi:10.4171/cmh/568
Abstract
We show that for any lattice Veech group in the mapping class group of a closed surface , the associated --extension group is a hierarchically hyperbolic group. As a consequence, we prove that any such extension group is quasi-isometrically rigid.
