摘要：
Consider the second order discrete Hamiltonian systems Delta(2)u(n - 1) - L(n)u(n) + del W(n, u(n)) = f(n), n is an element of Z, u is an element of R-N and W : Z x R-N --> R and f : Z --> R-N are not necessarily periodic in n. Under some comparatively general assumptions on L, W and f, we establish results on the existence of homoclinic orbits. The obtained results successfully generalize those for the scalar case.
