Stability of variational eigenvalues for the fractional p-Laplacian

Abstract

By virtue of Γ-convergence arguments, we investigate the stability of variational eigenvalues associated with a given topological index for the fractional p-Laplacian operator, in the singular limit as the nonlocal operator converges to the p-Laplacian. We also obtain the convergence of the corresponding normalized eigenfunctions in a suitable fractional norm.
