Abstract : The focus of this research is the filtering jump processes. To investigate the filtering of manifold valued processes, their approximation by random walks and Markov chains was studied. The object was to approximate a signal process by a finitestate jump process for which a finite dimensional filter is available. The Partially Observed Stochastic Minimum Principle: A minimum principle for a partially observed diffusion can be obtained by differentiating the statement that a control u* is optimal. The results on stochastic flows enable us to compute in an easy and explicit way the change in the cost due to a strong variation of an optical control. The only technical difficulty is the justification of the differentiation.
