A posteriori error analysis and adaptivity for high-dimensional elliptic and parabolic boundary value problems

F Merle, A Prohl - Numerische Mathematik, 2023 - Springer
We derive a posteriori error estimates for the (stopped) weak Euler method to discretize SDE
systems which emerge from the probabilistic reformulation of elliptic and parabolic (initial) …
