Title:Invariant distributions in elliptic dynamics,II
Seminar:Working Seminar: Dynamics and its Working Tools
Speaker:Alejandro Kocsard, Fluminense Federal University, Brazil
Abstract:
Invariant distributions appear as natural obstructions for the existence of smooth solutions for cohomological equations and they have been extensively used for estimating ergodic deviations, especially for certain parabolic and hyperbolic systems. In general, such systems exhibit infinitely many invariant distributions. On the other hand, within elliptic dynamical systems ergodic rigid translations on tori are the archetypal examples of such systems and they are distributionally uniquely ergodic, i.e. the Lebesgue measure is the only (up to multiplication by a constant) invariant distribution. In these talks we shall discuss some results and conjectures about distributionally uniquely ergodic systems.
