چکیده

Since Pardoux and Peng introduced backward stochastic differential equations (BSDEs in short), the theory of BSDEs has been widely developed, mainly because of a large part of problems in mathematical finance can be treated as a BSDE. However it is known that only a limited number of BSDE can be solved explicitly. To develop numerical method and numerical algorithm is very helpful, theoretically and practically. Recently many different types of discretization of BDSDE and the related numerical analysis were introduced. On the other hand, Paroux and Peng [8] introduced a new class of backward stochastic differential equations-backward ”doubly” stochastic differential equations and also showed the existence and uniqueness of the solution of BDSDE. But until now little work is devoted to the numerical method and the related numerical analysis. Here following the approach of Mémin, Peng and Xu [5], we present two numerical schemes of approximating solutions of BDSDE, and

Generalized backward doubly stochastic differential equations and SPDEs with nonlinear Neumann boundary conditions

Backward stochastic differential equations (BSDEs) were introduced by Pardoux and Peng [6], and it was shown in various papers that stochastic differential equations (SDEs) of this type give a probabilistic representation for the solution (at least in the viscosity sense) of a large class of system of semi-linear parabolic partial differential equations (PDEs). A new class of BSDEs, called back...

Backward doubly stochastic differential equations and systems of quasilinear SPDEs

A new kind of backward stochastic differential equations (in short BSDE), where the solution is a pair of processes adapted to the past of the driving Brownian motion, has been introduced by the authors in [63. It was then shown in a series of papers by the second and both authors (see [8, 7, 9, 103), that this kind of backward SDEs gives a probabilistic representation for the solution of a lar...

Unified Systems of FB-SPDEs/FB-SDEs with Jumps/Skew Reflections and Stochastic Differential Games

Abstract We study four systems and their interactions. First, we formulate a unified system of coupled forward-backward stochastic partial differential equations (FB-SPDEs) with Lévy jumps, whose drift, diffusion, and jump coefficients may involve partial differential operators. An solution to the FB-SPDEs is defined by a 4-tuple general dimensional random vector-field process evolving in time ...

Pathwise Stationary Solutions of Stochastic Partial Differential Equations and Backward Doubly Stochastic Differential Equations on Infinite Horizon

The main purpose of this paper is to study the existence of stationary solution for stochastic partial differential equations. We establish a new connection between backward doubly stochastic differential equations on infinite time horizon and the stationary solution of the SPDEs. For this we study the existence of the solution of the associated BDSDEs on infinite time horizon and prove it is a...
