On approximation of the Dirichlet problem for divergence form operator by Robin problems
Andrzej Rozkosz, Leszek Slominski · 2022-05-17 · via math.PR updates on arXiv.org

We show, that under natural assumptions, solutions of Dirichlet problems for uniformly elliptic divergence form operator can be approximated pointwise by solutions of some versions of Robin problems. The proof is based on stochastic representation of solutions and properties of reflected diffusions corresponding to divergence form operators.
