Eigenvalues of the Finsler -Laplacian on varying domains
Giuseppina di Blasio, Pier Domenico Lamberti
We study the dependence of the first eigenvalue of the Finsler -Laplacian and the corresponding eigenfunctions upon perturbation of the domain and we generalize a few results kn…

On a Babuška paradox for polyharmonic operators: spectral stability and boundary homogenization for intermediate problems
Francesco Ferraresso, Pier Domenico Lamberti
We analyse the spectral convergence of high order elliptic differential operators subject to singular domain perturbations and homogeneous boundary conditions of intermediate type.…
