Goncalves Universidade Federal de Goiás, Instituto de Matemática e Estatística, 74001-970 Goiania (GO), Brasil jv@mat.unb.br We employ variational methods for non-smooth functionals to show existence of multiple solutions for multivalued fourth order elliptic equations under Navier boundary conditions. Our main result extends similar ones known for the Laplacian. Keywords: Elliptic resonant problems, multiple solutions, non-smooth functionals.
