In this article, we establish sufficient conditions for the existence of homoclinic solutions for a class of second-order Hamiltonian systems
where L(t) is a positive definite symmetric matrix for all . It is worth pointing out that the potential function W(t,u) is locally defined and can be superquadratic or subquadratic with respect to u.
