Abstract

We introduce a topometric version of Lipschitz-free spaces and study its universal property. Another aim of this paper is to investigate actions of topological groups G on Lipschitz-free spaces F(M), induced by isometric actions on pointed metric spaces M. In particular, we study the associated dynamical G-systems under the weak-star topology, focusing on the dual action on Lip0(M) = F(M)^* and the bidual F(M)**.
