Abstract
In this paper, a class of second order discrete Hamiltonian systems with periodicity
assumptions is considered. Based on the critical point theory, some sufficient conditions
for the existence of subharmonic solutions and homoclinic orbits are obtained. The results
obtained extend the results in 2007 by relaxing the assumptions on the sign of the
potential.
