Abstract

The existence of solutions of the equation Lx = Nx, where L is a Fredliolm linear operator of index zero and N is a nonlinear continuous map, is established. N is sublinear Landesman-Lazer ones. The results are applied to boundary value problems with nonlinearities also involving derivatives. The resonance can be multidimensional.
