Near-Integrability of Periodic Klein-Gordon Lattices
In this paper, we study the Klein-Gordon (KG) lattice with periodic boundary conditions. It is an <i>N</i> degrees of freedom Hamiltonian system with linear inter-site forces and nonlinear on-site potential, which here is taken to be of the <inline-formula> <math display="i...
