摘要：
This paper concerns the control of diffusions under partial observations. Part I studies the control of the signal process dXt=b(t,Xt,Ut)dt+σ(t,Xt,Ut)dBt. The existence of an optimal relaxed control is proved. Part II studies the separated problem and proves the existence of an optimal Markovian filter. Then, the authors compare the two problems and prove, under mild conditions, that the value functions for the two problems are equal.
