[en] In this paper, we prove, using Malliavin calculus, that
under a global Hormander condition the law of a Riemannian manifold
valued stochastic process, a solution of a stochastic differential
equation with time dependent coefficients, admits a smooth density with
respect to the Riemannian volume element. This result is applied to
a nonlinear filtering problem with time dependent coefficients on
manifolds.
