Stochastic Perturbation of Sweeping Process and a Convergence Result for an Associated Numerical Scheme

چکیده
— Here we present well-posedness results for first order stochastic differential inclusions, more precisely for sweeping process with a stochastic perturbation. These results are provided in combining both deterministic sweeping process theory (recently developed in [18] and [19]) and methods concerning the reflection of a Brownian motion ([23] and [31]). In addition, we prove convergence results for a Euler scheme, discretizing theses stochastic differential inclusions. Résumé. — Nous démontrons dans ce travail le caractère “bien-posé” d’inclusions différentielles stochastiques du premier ordre, plus précisément de processus de rafle avec une perturbation stochastique. Ces résultats sont issus de l’association de la théorie des processus de rafle déterministes (récemment développée [18] et [19]) et de méthodes concernant la réflexion d’un mouvement brownien ([23] et [31]). De plus, nous prouvons un résultat de convergence pour un schéma d’Euler, discrétisant ces inclusions différentielles stochastiques.

Approximation of stochastic advection diffusion equations with finite difference scheme
In this paper, a high-order and conditionally stable stochastic difference scheme is proposed for the numerical solution of $rm Ithat{o}$ stochastic advection diffusion equation with one dimensional white noise process. We applied a finite difference approximation of fourth-order for discretizing space spatial derivative of this equation. The main properties of deterministic difference schemes,...
متن کاملThe Effects of Different SDE Calculus on Dynamics of Nano-Aerosols Motion in Two Phase Flow Systems
Langevin equation for a nano-particle suspended in a laminar fluid flow was analytically studied. The Brownian motion generated from molecular bombardment was taken as a Wiener stochastic process and approximated by a Gaussian white noise. Euler-Maruyama method was used to solve the Langevin equation numerically. The accuracy of Brownian simulation was checked by performing a series of simulati...

A Legendre wavelet method is presented for numerical solutions of stochastic Volterra-Fredholm integral equations.

In this paper, we apply Legendre wavelet collocation method to obtain the approximate solution of nonlinear Stratonovich Volterra integral equations. The main advantage of this method is that Legendre wavelet has orthogonality property and therefore coefficients of expansion are easily calculated. By using this method, the solution of nonlinear Stratonovich Volterra integral equation reduces to...
