Stochastic optimal control problem with infinite horizon driven by G-Brownian motion
The present paper considers a stochastic optimal control problem, in which
the cost function is defined through a backward stochastic differential
equation with infinite horizon driven by G-Brownian motion. Then we study the
regularities of the value function and establish the dynamic programming
principle. Moreover, we prove that the value function is the uniqueness
viscosity solution of the related HJBI equation
BSDE, Path-dependent PDE and Nonlinear Feynman-Kac Formula
In this paper, we introduce a type of path-dependent quasilinear (parabolic)
partial differential equations in which the (continuous) paths on an interval
[0,t] becomes the basic variables in the place of classical variables
(t,x). This new type of PDE are formulated through a classical backward
stochastic differential equation (BSDEs, for short) in which the terminal
values and the generators are allowed to be general functions of Brownian
paths. In this way we have established a new type of nonlinear Feynman-Kac
formula for a general non-Markovian BSDE. Some main properties of regularities
for this new PDE was obtained
Multi-dimensional BSDEs with mean reflection
In this paper, we consider multi-dimensional mean reflected backward stochastic differential equations (BSDEs) with possibly non-convex reflection domains along inward normal direction, which were introduced by Briand, Elie and Hu [6] in the scalar case. We first apply a fixed-point argument to establish the uniqueness and existence result under an additional bounded condition on the driver. Then, with the help of a priori estimates, we develop a successive approximation procedure to remove the additional bounded condition for the general case
General Mean Reflected BSDEs
The present paper is devoted to the study of backward stochastic differential
equations with mean reflection formulated by Briand et al. [7]. We investigate
the solvability of a generalized mean reflected BSDE, whose driver also depends
on the distribution of the solution term . Using a fixed-point argument, BMO
martingale theory and the -method, we establish the existence and
uniqueness result for such BSDEs in several typical situations, including the
case where the driver is quadratic with bounded or unbounded terminal
condition.Comment: 20 page
