In this paper we study the existence of nontrivial solutions for the periodic discrete nonlinear equation Lun-un=ωfn(un),where Lun=an+1un+an-1un-1+bnunis the discrete Laplacian in one spatial dimension. The give...

In this paper we consider the first order discrete Hamiltonian systems {x1(n+1)-x1(n)=Hx2(n,x(n)),x2(n)-x2(n-1)=Hx1(n,x(n)),where x(n) = (x2(n)x1(n))∑ R^2N, H(n,z) = 1/2S(n)z. z + R(n,z...
