Local rigidity of affine actions of higher rank groups and lattices

David Fisher, Gregory Margulis

Let $J$ be a semisimple Lie group with all simple factors of real rank at least two. Let $Γ < J$ be a lattice. We prove a very general local rigidity result about actions of $J$ or $…

Almost isometric actions, property $(T)$ , and local rigidity

David Fisher, G. A. Margulis

Let $Γ$ be a discrete group with property $(T)$ of Kazhdan. We prove that any Riemannian isometric action of $Γ$ on a compact manifold $X$ is locally rigid. We also prove a more ge…

Local Rigidity for Cocycles

David Fisher, G. A. Margulis

In this paper we study perturbations of constant cocycles for actions of higher rank semi-simple algebraic groups and their lattices. Roughly speaking, for ergodic actions, Zimmer'…
