Title: Relative rotation number for stochastic systems: dynamical and topological applications
Author: Catuogno, P
Ledesma, DS
Ruffino, P
Abstract: We introduce a concept of relative rotation number to unify many different approaches of rotation number in non-linear dynamical systems. We present an ergodic result of existence a.s. for stochastic systems. In higher dimension, we show that the natural idea of projecting into a plane does work well a.s. for any plane (different from deterministic systems where projections may be degenerate). A number of further properties (invariance by homotopy and by conjugacy) and applications are presented.
