Semilinear equations for non-local operators: beyond the fractional Laplacian
Ivan Biočić, Zoran Vondraček, Vanja Wagner
We study semilinear problems in general bounded open sets for non-local operators with exterior and boundary conditions. The operators are more general than the fractional Laplacia…

Nonlocal quadratic forms with visibility constraint
Moritz Kassmann, Vanja Wagner
Given a subset of the Euclidean space, we study nonlocal quadratic forms that take into account tuples if and only if the line segment between and $y…
