摘要
A new result for the existence of homoclinic orbits is obtained for the second-order Hamiltonian system u(t) = del F (t, u(t)) + f(t), where t is an element of R, u is an element of R(n), F is an element of C(1)(R x R(n), R) is T-periodic with respect to t, T > 0 and f : R -> R(n) is a continuous and bounded function. This result generalizes and improves some known results in the previous literature. (C) 2009 Elsevier Ltd. All rights reserved.
