Nonlocal critical problems with mixed boundary conditions and nearly resonant perturbations

Eduardo Colorado, Giovanni Monica Bisci, Alejandro Ortega +1

We consider the following nonlocal critical problem with mixed Dirichlet-Neumann boundary conditions, \begin{equation} \left\{ \begin{array}{ll} (-Δ)^su=λu+|u|^{2_s^*-2}u &\text{in…
