On stochasticity in nearly-elastic systems
Mark Freidlin, Wenqing Hu
Nearly-elastic model systems with one or two degrees of freedom are considered: the system is undergoing a small loss of energy in each collision with the "wall". We show that inst…

Smoluchowski-Kramers approximation in the case of variable friction
Mark Freidlin, Wenqing Hu
We consider the small mass asymptotics (Smoluchowski-Kramers approximation) for the Langevin equation with a variable friction coefficient. The limit of the solution in the classic…

On perturbations of generalized Landau-Lifshitz dynamics
Mark Freidlin, Wenqing Hu
We consider deterministic and stochastic perturbations of dynamical systems with conservation laws in . The Landau-Lifshitz equation for the magnetization dynamics in ferroma…
