Symplectic integration of Sine-Gordon type systems
We construct a class of symplectic integration schemes to general Sine-Gordon type systems. We also conduct several numerical tests for these symplectic schemes. Our numerical results demonstrate the effectiveness of these schemes for numerical computation of the solutions to the general Sine-Gordon type systems. (C) 1999 IMACS/Elsevier Science B.V.
