Abstract
. An existence result for positive solutions to a fourth order differential inclusion with boundary values is given. This is accomplished by using a fi xed point theorem on cones for multivalued maps, L 1 selections and a generalization of the Ascoli theorem. The inclusion allows the function and its fi rst three derivatives to be on the right-hand side. The proof involves a Green’s function and a positive eigenvalue of a particular operator. An example is provided.
