Uniqueness of the filtering equations in the space of measures

Apparaît dans la collection : Probability/PDE Interactions: Interface Models and Particle Systems / Interactions EDP/Probabilités : interfaces et systèmes de particules

We consider a general class of filtering equations, where all coefficients depend upon the observation process, and the signal and observation noises are correlated. We prove uniqueness of the measure valued solution of the Zakai equation via a duality argument with a backward stochastic partial differential equation. This is joint work with Dan Crisan, Imperial College, London.
