Stability of densities for perturbed degenerate diffusions

We study the sensitivity of the densities of some Kolmogorov-like degenerate diffusion processes with respect to a perturbation of the coefficients of the nondegenerate component. Under suitable (quite sharp) assumptions we quantify how the perturbation of the SDE affects the density. Natural appli...

520 |a We study the sensitivity of the densities of some Kolmogorov-like degenerate diffusion processes with respect to a perturbation of the coefficients of the nondegenerate component. Under suitable (quite sharp) assumptions we quantify how the perturbation of the SDE affects the density. Natural applications of these results appear in various fields from mathematical finance to kinetic models.
