The existence of multiple solutions u is an element of H-0(1)(Omega) to a differential inclusion of the type -Delta u is an element of partial derivative J (x, u) in Omega, where partial derivative J (x,.) denotes the generalized sub-differential of J (x, .), is investigated through critical point theorems for locally Lipschitz continuous functionals on closed convex sets of a Hilbert space.
