Abstract :
[en] In this paper, we derive the Kushner-Stratonovich and
the Zakai equation for the lter and the unnormalized
lter associated with a nonlinear ltering problem with
correlated noises, bounded coe cients and a signal process
evolving in an in nite dimensional space. A robust form
of the Zakai equation is established when the noises are
independent.
