Asymptotic Dimension of Big Mapping Class Groups
Curtis Grant, Kasra Rafi, Yvon Verberne
Even though big mapping class groups are not countably generated, certain big mapping class groups can be generated by a coarsely bounded set and have a well defined quasi-isometry…
Automorphisms of the fine curve graph
Adele Long, Dan Margalit, Anna Pham +2
Building on work of Farb and the second author, we prove that the group of automorphisms of the fine curve graph for a surface is isomorphic to the group of homeomorphisms of the s…
Stable specific torsion length and periodic mapping classes
Elizabeth Field, Yvon Verberne
We show that for any periodic mapping class, there is some power which maps a nonseparating, simple closed curve to a distinct, disjoint nonseparating curve. As an application of t…
Finite image homomorphisms of the braid group and its generalizations
Nancy Scherich, Yvon Verberne
Using totally symmetric sets, Chudnovsky, Kordek, Li, and Partin gave a superexponential lower bound on the cardinality of non-abelian finite quotients of the braid group. In this…
