Random Perturbations of 2-dimensional Hamiltonian Flows
We consider the motion of a particle in a periodic two dimensional flow perturbed by small (molecular) diffusion. The flow is generated by a divergence free zero mean vector field. The long time behavior corresponds to the behavior of the homogenized process that is diffusion process with the constant diffusion matrix (effective diffusivity). We obtain the asymptotics of the effective diffusivi...

متن کاملSingular Perturbations of Finite Dimensional Gradient Flows
In this paper we give a description of the asymptotic behavior, as ε → 0, of the ε-gradient flow in the finite dimensional case. Under very general assumptions we prove that it converges to an evolution obtained by connecting some smooth branches of solutions to the equilibrium equation (slow dynamics) through some heteroclinic solutions of the gradient flow (fast dynamics).

متن کاملApproximating multi-dimensional Hamiltonian flows by billiards
The behavior of a point particle traveling with a constant speed in a region D ∈ RN , undergoing elastic collisions at the regions’s boundary, is known as the billiard problem. Various billiard models serve as approximation to the classical and semi-classical motion in systems with steep potentials (e.g. for studying classical molecular dynamics, cold atom’s motion in dark optical traps and mic...
