Abstract: 
Homoclinic orbits play an important role in the study of qualitative
behavior of dynamical systems. Such kinds of orbits have been studied
since the time of Poincare.
In this paper, we discuss how to use variational methods to study the
existence of homoclinic orbits of Hamiltonian systems.
