Multisymplectic Pseudospectral Discretizations for(3+1)-Dimensional Klein-Gordon Equation被引量:1
《Communications in Theoretical Physics》2008年第11期1052-1054,共3页CHEN Jing-Bo LIU Hong 
supported by National Natural Science Foundation of China under Grant No.40774069;partially by the National Hi-Tech Research and Development Program of China under Crant No.2006AA09A102-08;State Key Basic Research Program under Grant No.2007CB209603
We explore the multisymplectic Fourier pseudospectral discretizations for the (3+1)-dimensional Klein-Gordon equation in this paper.The corresponding multisymplectic conservation laws are derived.Two kinds of explicit...
