Highly Transitive Actions of Surface Groups

Group Theory 2009-11-17 v2

Abstract

A group action is said to be highly-transitive if it is kk-transitive for every k1k \ge 1. The main result of this thesis is the following: Main Theorem: The fundamental group of a closed, orientable surface of genus > 1 admits a faithfull, highly-transitive action on a countably infinite set. From a topological point of view, finding a faithfull, highly-transitive action of a surface group is equivalent to finding an embedding of the surface group into Sym(Z)Sym(Z) with a dense image. In this topological setting, we use methods originally developed in [3] and [1] for densely embedding surface groups in locally compact groups.
