Abstract:
We explore the numerical approximation of the stochastic Burgers equation driven by fractional Brownian motion with Hurst index H ∈ (1/4, 1/2) and H ∈ (1/2, 1), respectively. The spatial and temporal regularity properties for the solution are obtained. The given problem is discretized in time with the implicit Euler scheme and in space with the standard finite element method. We obtain the strong convergence of semidiscrete and fully discrete schemes, performing the error estimates on a subset Ωk, h of the sample space Ω with the Gronwall argument being used to overcome the difficulties, caused by the subtle interplay of the nonlinear convection term. Numerical examples confirm our theoretical findings. © 2024 the Author(s), licensee AIMS Press.
