A Stochastic Finite Element Method for Stochastic Parabolic Equations Driven by Purely Spatial Noise
نویسندگان
چکیده
We consider parabolic SPDEs driven by purely spatial noise, and show the existence of solutions with random initial data and forcing terms. We perform error analysis for the semi-discrete stochastic finite element method applied to a class of equations with self-adjoint differential operators that are independent of time. The analysis employs the formal stochastic adjoint problem and the corresponding elliptic error estimates to obtain the optimal order of convergence (in space).

We study stochastic parabolic and elliptic PDEs driven by purely spatial white noise. Even the simplest equations driven by this noise often do not have a square-integrable solution and must be solved in special weighted spaces. We demonstrate that the Cameron-Martin version of the Wiener chaos decomposition is an effective tool to study both stationary and evolution equations driven by space-o...

متن کاملComputational Method for Fractional-Order Stochastic Delay Differential Equations
Dynamic systems in many branches of science and industry are often perturbed by various types of environmental noise. Analysis of this class of models are very popular among researchers. In this paper, we present a method for approximating solution of fractional-order stochastic delay differential equations driven by Brownian motion. The fractional derivatives are considered in the Caputo sense...
متن کاملA Finite Element Method for Martingale-driven Stochastic Partial Differential Equations
The main objective of this work is to describe a Galerkin approximation for stochastic partial differential equations driven by square– integrable martingales. Error estimates in the semidiscrete case, where discretization is only done in space, and in the fully discrete case are derived. Parabolic as well as transport equations are studied.
