Earth Sciences (MIFT) of the University of Messina, Italy.

摘      要：

       We consider a linearly perturbed elliptic problem governed by the spectral fractional Laplacian and with mixed Dirichlet–Neumann boundary data. The nonlinearity is considered both in the subcritical and in the critical regime. By using linking and variational theorems of mixed type (one of the so called ∇-theorems), we prove the existence of multiple solutions when the perturbation parameter is close to the eigenvalues of the operator.
