Abstract

Consider a family of random ordinary differential equations on a manifold driven by vector fields of the form \(\sum _kY_k\alpha _k(z_t^\epsilon (\omega ))\) where \(Y_k\) are vector fields, \(\epsilon \) is a positive number, \(z_t^\epsilon \) is a \({1\over \epsilon } {\mathcal {L}}_0\) diffusion process taking values in possibly a different manifold, \(\alpha _k\) are annihilators of \(\mathrm{ker}({\mathcal {L}}_0^*)\). Under Hörmander type conditions on \({\mathcal {L}}_0\) we prove that, as \(\epsilon \) approaches zero, the stochastic processes \(y_{t\over \epsilon }^\epsilon \) converge weakly and in the Wasserstein topologies. We describe this limit and give an upper bound for the rate of the convergence.
