    Stochastic Maximum Principle

    No full text
    International audienceThe stochastic maximum principle (SMP) gives some necessary conditions for optimality for a stochastic optimal control problem. We give a summary of well-known results concerning stochastic maximum principle in finite-dimensional state space as well as some recent developments in infinite-dimensional state space

    A general characterization of the stochastic optimal combined control of mean field stochastic systems with application

    No full text
    In this paper, a general characterization of the optimal stochastic combined control for mean-field jump-systems is derived by applying mixed convex-spike perturbation method. The diffusion coefficient depends on the continuous control variable and the coDepartment of Mathematics, Yasar University, University aven, Agaclı Yol No. 35-57, Izmir, Turkey; Laboratory of Applied Mathematics, Biskra University, PO.
