A maximum principle for progressive optimal control of mean-filed forward-backward stochastic system involving random jumps and impulse controls
In this paper, we study an optimal control problem of a mean-field
forward-backward stochastic system with random jumps in progressive structure,
where both regular and singular controls are considered in our formula. In
virtue of the variational technology, the related stochastic maximum principle
(SMP) has been obtained, and it is essentially different from that in the
classical predictable structure. Specifically, there are three parts in our
SMP, i.e. continuous part, jump part and impulse part, and they are
respectively used to characterize the characteristics of the optimal controls
at continuous time, jump time and impulse time. This shows that the progressive
structure can more accurately describe the characteristics of the optimal
control at the jump time. We also give two linear-quadratic (LQ) examples to
show the significance of our results
On Maximum Principle of Non Linear Stochastic Mckean-Vlasov System with Applications Presented
Partially observed optimal control problem has a variety of important applications in many fields and offers practical avenues for addressing real-world control challenges and decision-making problems, such as engineering, economics, and finance.
The aim of this thesis is to study this kind of partially observed optimal control problem for forward-backward stochastic differential equations of the McKean– Vlasov type. The coefficients of the system and the cost functional depend on the state of the solution
process as well as of its probability law and the control variable. We start by defining the primary tool (the partial derivative with respect to the probability measure in Wasserstein space) used to illustrate our main result.
Then, we prove the necessary and sufficient conditions of optimality for FBSDEs of the McKean– Vlasov type under the assumption that the control domain is supposed to be convex. This result is based on Girsavov’s theorem. Finally, we prove a stochastic maximum principle for this kind of partially observed optimal control problems of McKean– Vlasov type driven by a Poisson random measure and an independent Brownian motion. As an illustration, a partially observed linear–quadratic control problem is studied in terms of stochastic filtering
