چکیده

We consider a class of Backward Stochastic Differential Equations with superlinear driver process f adapted to filtration supporting at least d dimensional Brownian motion and Poisson random measure on Rm∖{0}. the following terminal conditions: ξ1=∞⋅1{τ1≤T} where τ1 is any stopping time bounded density in neighborhood T ξ2=∞⋅1AT At, t∈[0,T] decreasing sequence events Ft that continuous probability (equivalently, AT={τ2>T} τ2 such P(τ2=T)=0). In this setting we prove minimal supersolutions BSDE are fact solutions, i.e., they attain almost surely their values. note first exit from varying domain d-dimensional diffusion driven by strongly elliptic covariance matrix does have density. Therefore times can be used as define conditions ξ1 ξ2. The proof existence based classical Green’s functions for associated PDE.

A Non-Markovian Liquidation Problem and Backward SPDEs with Singular Terminal Conditions

We establish existence, uniqueness and regularity of solution results for a class of backward stochastic partial differential equations with singular terminal condition. The equation describes the value function of non-Markovian stochastic optimal control problem in which the terminal state of the controlled process is pre-specified. The analysis of such control problems is motivated by models ...

Two algorithms for the discrete time approximation of Markovian backward stochastic differential equations under local conditions

Two discretizations of a novel class of Markovian backward stochastic differential equations (BSDEs) are studied. The first is the classical Euler scheme which approximates a projection of the processes Z, and the second a novel scheme based on Malliavin weights which approximates the mariginals of the process Z directly. Extending the representation theorem of Ma and Zhang [MZ02] leads to adva...

Singular Forward-Backward Stochastic Differential Equations and Emissions Derivatives

We introduce two simple models of forward-backward stochastic differential equations with a singular terminal condition and we explain how and why they appear naturally as models for the valuation of CO2 emission allowances. Single phase cap-and-trade schemes lead readily to terminal conditions given by indicator functions of the forward component, and using fine partial differential equations ...

Linear regression MDP scheme for discrete backward stochastic differential equations under general conditions

We design a numerical scheme for solving the Multi step-forward Dynamic Programming (MDP) equation arising from the time-discretization of backward stochastic differential equations. The generator is assumed to be locally Lipschitz, which includes some cases of quadratic drivers. When the large sequence of conditional expectations is computed using empirical least-squares regressions, under gen...

Stochastic Functional Differential Equations with Markovian Switching

The main aim of this paper is to investigate the exponential stability of stochastic functional differential equations with Markovian switching. The Razumikhin argument and the generalized Itô formula will play their important roles in this paper. Applying our new results to several important types of equations e.g. stochastic differential delay equations and stochastic differential equations, ...
