Abstract: Combining the method of upper and lower solutions with the topological degree, we show the existence of solutions satisfying periodic or Dirichlet boundary conditions, for a second order differential inclusion with phi-laplacian, where the right-hand side is a compact lower semi-continuous multi-valued map and phi si an homomeomorphism.
