Abstract:

In this article, we study the smooth mapping class group of a surface $S$ relative to a given Cantor set, that is, the group of isotopy classes of orientation-preserving smooth diffeomorphisms of $S$ which preserve this Cantor set. When the Cantor set is the standard ternary Cantor set, we prove that this group does not contain any distorted element. Moreover, we prove a weak Tits alternative for these groups.
