Estimates for multiple stochastic integrals and stochastic Hamilton-Jacobi equations [PDF]

open access: yes, 2004
We study stochastic Hamilton-Jacobi-Bellman equations and the corresponding Hamiltonian systems driven by jump-type Lévy processes. The main objective of the present paper is to show existence, uniqueness and a (locally in time) diffeomorphism ...

Equations Related to Stochastic Processes: Semigroup Approach and Fourier Transform

open access: yesСовременная математика: Фундаментальные направления, 2021
The work is devoted to integro-differential equations related to stochastic processes. We study the relationship between differential equations with random perturbations - stochastic differential equations (SDEs) - and deterministic equations for the ...

On stochastic differential equations and a generalised Burgers equation [PDF]

open access: yes, 2012
In this paper, we discuss a link of Itˆo’s stochastic differential equa- tions to nonlinear partial differential equations of Burgers type. Un- der certain conditions, we derive a generalised Burgers equation from a stochastic differential equation.

Approximate solutions of hybrid stochastic pantograph equations with Levy jumps [PDF]

open access: yes, 2013
We investigate a class of stochastic pantograph differential equations with Markovian switching and Levy jumps. We prove that the approximate solutions converge to the true solutions in 퐿 2 sense as well as in probability under local Lipschitz condition ...

Fractional SDEs with stochastic forcing: Existence, uniqueness, and approximation

open access: yesNonlinear Analysis, 2023
In this article, we are interested in fractional stochastic differential equations (FSDEs) with stochastic forcing, i.e., to FSDE we add a stochastic forcing term.

Delayed Stochastic Linear-Quadratic Control Problem and Related Applications

open access: yesJournal of Applied Mathematics, 2012
We discuss a quadratic criterion optimal control problem for stochastic linear system with delay in both state and control variables. This problem will lead to a kind of generalized forward-backward stochastic differential equations (FBSDEs) with Itô’s ...

Discrete Razumikhin-type technique and stability of the Euler-Maruyama method to stochastic functional differential equations [PDF]

open access: yes, 2013
A discrete stochastic Razumikhin-type theorem is established to investigate whether the Euler--Maruyama (EM) scheme can reproduce the moment exponential stability of exact solutions of stochastic functional differential equations (SFDEs).
