Abstract
In this paper we consider a class of periodic problems associated with 2N-dimensional systems of differential equations. Our aim is to generalize the theory of lower and upper solutions following the way paved in previous works. After a careful analysis of the dynamics in the phase space, the proofs take advantage of topological degree arguments.File in questo prodotto:
