Let (M, ( } , } ) R ) be a Riemannian manifold and V: M Ä R a C 2 potential function. The research of periodic solutions of the system where D t (x\* (t)) is the covariant derivative of x\* along the direction of x\* and { R the Riemannian gradient, has been studied when M is a noncontractible mani
