We study the existence of infinitely many homoclinic orbits for some second-order Hamiltonian systems: ΓΌ -L(t)u(t) + βˆ‡ F(t, u(t)) = 0, βˆ€t ∈ R, by the variant fountain Theorem, where F(t, u) satisfies the super-quadratic condition F(t, u)/|u| 2 β†’ ∞ as |u| β†’ ∞ uniformly in t, and need not satisfy the
