Groups acting on manifolds: around the Zimmer program

D Fisher - Geometry, rigidity, and group actions, 2011 - degruyter.com
This paper is a survey on the Zimmer program. In its broadest form, this program seeks an
understanding of actions of large groups on compact manifolds. The goals of this survey are …

Cocycle superrigidity and harmonic maps with infinite-dimensional targets

D Fisher, T Hitchman - International Mathematics Research …, 2006 - academic.oup.com
We announce a generalization of Zimmer's cocycle superrigidity theorem proven using
harmonic map techniques. This allows us to generalize many results concerning higher-rank …
