Outline of Final Research Achievements |
We obtained a local rigidity result for certain group action related to the rank-1 Lie group SO(n,1) with n>1 and a description of deformation of certain group action on the torus which preserves a geometric structure. The latter was an application of a method to show a rigidity result for a conformal action on the sphere. We also proved the abundance of super-exponential growth of the number of periodic points and existence of universal dynamics for one-dimensional iterated function systems which satisfies some mild conditions. One-dimensional iterated function systems are toy models of partially hyperbolic dynamical systems. Hence, our result is a step to understand wild behavior of partially hyperbolic systems.
