In this paper we establish a multiplicity result for a second order nonautonomous system. By using a variational principle by B. Ricceri we prove that if the set of global minima of a certain function has at least $k$ connected components then our problem has at least $k$ periodic solutions. Moreover, the existence of one more solution is investigated through a mountain pass-like argument.

Abstract
In this paper we establish a multiplicity result for a second order nonautonomous system. By using a variational principle by B. Ricceri we prove that if the set of global minima of a certain function has at least $k$ connected components then our problem has at least $k$ periodic solutions. Moreover, the existence of one more solution is investigated through a mountain pass-like argument.File in questo prodotto:
