For a project I'm doing, I have to numerically solve a nonlinear parabolic stochastic partial differential equation, of the form $$ u_t = u_{xx} + f(u)(u_x)^2 + a(u) + b(u)W(t, x), $$ where primes a …

As it turns out, the $(u_x)^2$ term is ill-defined due to the irregularity of $u$, which is caused by the space-time white noise. This causes discrete approximations to converge to solutions to differ …
