Abstract
The random-phase approximation is rigorously proved for a particular m odel of modulated diffusion consisting in a 1D integrable Hamiltonian map whose phase is modulated by an external Markov noise. Continuity o f the diffusion coefficient in the limit of vanishing noise amplitude is also investigated.
