The idea is to perturb the dynamics by a noise acting only on some components of the ODE and propagating through the other ones thanks to a weak Hörmander like condition, as in the framework of Kolmogorov degeneracy. The noise we consider is a jump Lévy process (integro-differential framework for the generator of the noise). We are particularly interested in the minimal regularity assumptions on the coefficients leading to the weak well-posedness of the associated SDE. As an application, we apply our method to a Hamiltonian model arising from a mechanical problem involving friction. ==== Research themes === * Stochastic Analysis: Regularization by Noise, Degenerate systems, Lévy jump noises * PDE techniques: A priori Estimates, Schauder Estimates, Well-posedness for Integro-Partial Differential equations ==== Publications ==== * L.
