“…A systemic theory of symplectic integrators for Hamiltonian ODEs has been established by some authors. The Runge-Kutta methods play an important role in numerically solving differential equations (see [1], [3], [4], [6]- [16] and the references therein). The symplectic condition of Runge-Kutta methods was found independently by Lasagni, Sanz-Serna and Suris in 1988 (see [10], [12], [15] and the references therein).…”

“…Certain numerical methods (the symplectic and multisymplectic finite difference schemes and the spectral methods, etc.) are devoted to homogeneous nonlinear Klein-Gordon equations [26]- [30]. In [30] the authors propose a spectral method using as a basis the Legendre functions.…”
