Existence of optimal stochastic controls and global solutions of forward-backward stochastic differential equations

open access: yes, 2004
We consider an optimal stochastic control problem, assuming Lipschitz conditions and allowing degeneracy of the diffusion coefficient, under some structural constraint on the state equation.

Method of Successive Approximations for Stochastic Optimal Control: Contractivity and Convergence

open access: yes
The Method of Successive Approximations (MSA) is a fixed-point iterative method used to solve stochastic optimal control problems. It is an indirect method based on the conditions derived from the Stochastic Maximum Principle (SMP), an extension of the ...

Reflected backward stochastic differential equations driven by Lévy processes

open access: yes
In this paper, we deal with reflected backward stochastic differential equations driven by Teugels martingales associated with Lévy process satisfying some moment condition and an independent Brownian motion.

Invariant measures for stochastic heat equations with unbounded coefficients

open access: yes
The paper deals with the Cauchy problem in of a stochastic heat equation . The locally lipschitz drift coefficient f can have polynomial growth while the diffusion coefficient [sigma] is supposed to be lipschitz but not necessarily bounded.

Contribution to the Study of Backward SDEs and Their Applications to Stochastic Optimal Control [PDF]

open access: yes
In this thesis, we aim to generalize some existing results in the literature that concern a stochastic maximum principle for backward stochastic differential equations (BSDEs) or forward-backward stochastic differential equation (FBSDEs), with two ...
