Numerical methods for stochastic parabolic PDEs. (English) Zbl 0919.65100
This paper presents a proof of the convergence of finite difference approximations of the solution of the nonlinear stochastic partial differential equation initial value problem of the form \[ du(t)= \Biggl[{\partial^2u(t)\over\partial x^2}+ f(u(t))\Biggr] dt+ dB(t),\quad u(0)= U, \] where \(B(t)\) is a Wiener process. It concludes with a brief summary of results obtained in numerical experiments with \(f=0\) and with \(f= .5(u- u^3)\).
