Essential spectrum for the Laplacian

Lorenzo Brasco, Luca Briani, Giovanni Franzina

We introduce a variational notion of essential spectrum for the Dirichlet Laplacian. We then extend the classical Persson Theorem to this nonlinear setting. This result provide…

Low eigenvalues of the Laplacian in general open sets

Lorenzo Brasco, Luca Briani, Francesca Prinari

We consider the minmax Ljusternik-Schnirelmann levels of the constrained Dirichlet integral, on a general open set of the Euclidean space. We show that, whenever one of these l…
