| Abstract | T-periodic solutions of systems of differential equations of the form
 where φ = ∇Φ, with Φ strictly convex, is a homeomorphism of the ball
 onto  , are considered under various conditions upon F and h. The approach is mostly variational, but requires the use of results on an auxiliary system based upon fixed point theory and Leray-Schauder degree. |
