The Wiener criterion for nonlocal Dirichlet problems
arXiv:2203.16815 · doi:10.1007/s00220-023-04632-w
Abstract
We study the boundary behavior of solutions to the Dirichlet problems for integro-differential operators with order of differentiability and summability . We establish a nonlocal counterpart of the Wiener criterion, which characterizes a regular boundary point in terms of the nonlocal nonlinear potential theory.
