Partially observed jump diffusions $Z_t=(X_t,Y_t)$ on a time interval $[0,T]$ are considered. The classic problem of describing the mean square estimate for the `unobserved component’ $X_t$ from `past observations' $Y_s$, $s\leq t$ is discussed. Stochastic integro-differential equations for the conditional distribution $\mu_t(dx)$ of $X_t$, given the past observations, are shown, and recent results on the existence of the density $\mu_t(dx)/dx$ and its analytical properties are presented.
The talk is based on joint work with Sizhou Wu and Fabian Germ.
