We consider aseminonlinear Neumann problem driven by the p- Laplacian plus an indenite and unbounded potential. The reaction of the problem is resonant at ±∞ with respect to the higher parts of the spectrum. Using critical point theory, truncation and perturbation techniques, Morse theory and the reduction method, we prove two multiplicity theorems. One produces three nontrivial smooth solutions and the second four nontrivial smooth solutions.

Abstract
We consider aseminonlinear Neumann problem driven by the p- Laplacian plus an indenite and unbounded potential. The reaction of the problem is resonant at ±∞ with respect to the higher parts of the spectrum. Using critical point theory, truncation and perturbation techniques, Morse theory and the reduction method, we prove two multiplicity theorems. One produces three nontrivial smooth solutions and the second four nontrivial smooth solutions.File in questo prodotto:
