Local rigidity of group actions of isometries on compact Riemannian manifolds
Laurent Stolovitch, Zhiyan Zhao
In this article, we consider perturbations of isometries on a compact Riemannian manifold . We investigate the smooth (resp. analytic) rigidity phenomenon of groups of these iso…

Local rigidity of actions of isometries on compact real analytic Riemannian manifolds
Laurent Stolovitch, Zhiyan Zhao
In this article, we consider analytic perturbations of isometries of an analytic Riemannian manifold M. We prove that, under some conditions, a finitely presented group of such sma…
