摘要：

We study the existence and multiplicity of periodic solutions of the following second-order Hamiltonian system u(t) + del[-K(t, u(t)) + W(t, u(t))] = 0. The existence of a nontrivial periodic solution is obtained when del W is asymptotically linear at infinity, and the existence of infinitely many periodic solutions is also obtained when del W is superlinear.
