Abstract
In this paper we prove a multiplicity result for critical points of an indefinite functional on a manifold by using a generalization of the Ljusternik-Schnirelman category. The abstract result is applied to prove the existence of multiple timelike trajectories for Lorentzian manifolds of splitting typeFile in questo prodotto:
