heal.abstract	. In this paper we use the method of upper and lower solutionsto study multivalued Sturm--Liouville and periodic boundary value problems,with Caratheodory orientor field. We prove two existence theorems.One when the orientor field F (t; x; y) is convex--valued and the other whenF (t; x; y) is nonconvex valued. Finally we show that the &quot;convex&quot; problemhas extremal solutions in the	en
