  • We continue the ideas behind the proof of our key result, realizing it as a special of a more general machine for establishing local rigidity up to semi-conjugacy of group actions on spaces that can be formulated into the framework of a bundle structure with some additional properties. A principal component of this machine involves extending a construction of Bowden-Mann using barycenter maps. This is joint work with Mitul Islam, Thang Nguyen and Ralf Spatzier.
