Infinitely periodic solutions for a class second-order Hamiltonian systems

In this paper,we consider a class superlinear second order Hamiltonian systems,where the nonlinearity is odd.Under no Ambrosetti-Rabinowitz’s super quadratic condition,infinitely periodic solutions are obtained by using symmetric version mountain pass theorem.
