Stochastic Dynamics of Oscillator Drift in Media with Spatially Nonhomogeneous Friction

摘要

A mathematical model of forced oscillation dynamics of a stochastic oscillator on a plane with a nonlinear nonhomogeneous friction has been created. The dynamics of the oscillator Brownian walk which appears under a noise action in the direction orthogonal to direction of external driving force has been studied. A dependence of energy dissipation by the given oscillator on its Brownian walk dynamics has been determined.
