Abstract
We prove the existence of infinitely many solutions for a class of elliptic Dirichlet problems with non-symmetric nonlinearities. In particular, this result gives a positive answer to a well known conjecture formulated by A. Bahri and P.L. Lions, at least when the domains are cubes of Rn with n≥3. The proof is based on a minimization method which does not require the use of techniques of deformation from the symmetry. This method allows us to piece together solutions of Dirichlet problems in suitable subdomains, so we obtain infinitely many nodal solutions with a prescribed nodal structure.File | Dimensione | Formato | |
