A Proposed Stochastic Finite Difference Approach Based on Homogenous Chaos Expansion

open access: yesJournal of Applied Mathematics, 2013
This paper proposes a stochastic finite difference approach, based on homogenous chaos expansion (SFDHC). The said approach can handle time dependent nonlinear as well as linear systems with deterministic or stochastic initial and boundary conditions. In

A Stochastic Approach for Parameterizing Unresolved Scales in a System with Memory

open access: yesJournal of Algorithms & Computational Technology, 2009
Complex systems display variability over a broad range of spatial and temporal scales. Some scales are unresolved due to computational limitations. The impact of these unresolved scales on the resolved scales needs to be parameterized or taken into ...

New traveling wave solutions, phase portrait and chaotic pattern for the stochastic modified Korteweg–de Vries equation

open access: yesResults in Physics, 2023
This article mainly studies the new traveling wave solutions of the stochastic modified Korteweg–de Vries equation with multiplicative noise. The traveling wave solutions in the form of hyperbolic function, trigonometric function, rational function and ...

On the spatial dynamics of the solution to the stochastic heat equation [PDF]

open access: yes, 2013
We consider the solution of partial derivative(t)u = partial derivative(2)(x) u + partial derivative(x)partial derivative(t) B, (x, t) is an element of R x (0; infinity), subject to the initial condition u (x, 0) = 0; x is an element of R, where B is a ...

Representation of the Solution of Goursat Problem for Second Order Linear Stochastic Hyperbolic Differential Equations

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2021
The article considers second-order system of linear stochastic partial differential equations of hyperbolic type with Goursat boundary conditions. Earlier, in a number of papers, representations of the solution Goursat problem for linear stochastic ...

Hölder estimates of mild solutions for nonlocal SPDEs

open access: yesAdvances in Difference Equations, 2019
We consider nonlocal PDEs driven by additive white noises on Rd ${\mathbb{R}}^{d}$. For Lq $L^{q}$ integrable coefficients, we derive the existence and uniqueness, as well as Hölder continuity, of mild solutions.

Stochastic De Giorgi Iteration and Regularity of Stochastic Partial Differential Equation [PDF]

open access: yes, 2013
Under general conditions we show that the solution of a stochastic parabolic partial differential equation of the form \[ \partial_t u = \mathrm{div} (A \nabla u) + f(t,x, u) + g_i (t,x,u) \dot{w}^i_t \] is almost surely H\"older continuous in both space
