Spaces of orders of some one-relator groups

Group Theory 2018-12-19 v2 Dynamical Systems Representation Theory

Abstract

We show that certain orderable groups admit no isolated left orders. The groups we consider are cyclic amalgamations of a free group with a general orderable group, the HNN extensions of free groups over cyclic subgroups, and a particular class of one-relator groups. In order to prove the results about orders, we develop perturbation techniques for actions of these groups on the line.
