Stochastic global maximum principle for optimization with recursive utilities

Abstract: In this paper, we study the recursive stochastic optimal control problems. The control domain does not need to be convex, and the generator of the backward stochastic differential equation can contain z. We obtain the variational equations for backward stochastic differential equations, and then obtain the maximum principle which solves completely Peng's open problem.

“…Proof. The proof can be directly obtained by combining Proposition 2.1 in [15] and Lemma 2 in [7]. Now we state our main result, which provides the necessary condition for a control to be near-optimal with order ε 1 2 .…”

“…Note the adjoint equation (11) is a forward-backward stochastic differential equation whose solution consists of an 7-tuple process (k(·), p(·), q 1 (·), q 2 (·), r(·), R 1 (·), R 2 (·)). Under Assumptions 2.1 and 2.2, by Proposition 2.1 in [15] and Lemma 2 in [7] , it is easily to see that the adjoint equation (11) admits a unique solution (k(·), p(·), q 1 (·), q 2 (·), r(·), R 1 (·), R 2 (·)), also called the adjoint process corresponding the admissible pair (u(·); x(·), y(·), z 1 (·), z 2 (·), ρ(·)). Particularly, we write (k u (·), p u (·), q u 1 (·), q u 2 (·), r u (·), R u 1 (·), R u 2 (·)) for the adjoint processes associated with any admissible pair (u(·); x u (·), y u (·), z u 1 (·), z u 2 (·), ρ u (·)), whenever we want to emphasize the dependence of (k(·), p(·), q 1 (·), q 2 (·), r(·), R 1 (·), R 2 (·)).…”

“…There are two main obstacles met when f depending on z nonlinearly (see Yong [26]): What is the second-order variational equation and how to obtain the corresponding second-order adjoint equation? Hence, this open problem was not solved completely until 2017 by Hu [18]. Hu overcome the above two difficulties by building a new second-order Taylor expansion of the variation of Y .…”

“…Based on the previous works [18], [15], [16], [4], [5], a natural question is: Is it possible to develop the necessary condition for optimality of the general mean-field forward-backward control systems with delay? We confirmed the question.…”
