Lower Bounds and Non-Uniform Time Discretization for Approximation of Stochastic Heat Equations

14 years 28 days ago

We study algorithms for approximation of the mild solution of stochastic heat equations on the spatial domain ]0, 1[ d . The error of an algorithm is defined in L2-sense. We derive...
