A conservative Fourier pseudospectral algorithm for a coupled nonlinear Schrdinger system被引量：5
《Chinese Physics B》2013年第6期135-140,共6页蔡加祥 王雨顺 
supported by the National Natural Science Foundation of China (Grant Nos. 11201169 and 11271195);the National Basic Research Program of China (Grant No. 2010AA012304);the Natural Science Foundation of Jiangsu Education Bureau,China (Grant Nos. 10KJB110001 and 12KJB110002);the Qing Lan Project of Jiangsu Province of China
We derive a new method for a coupled nonlinear Schr/Sdinger system by using the square of first-order Fourier spectral differentiation matrix D1 instead of traditional second-order Fourier spectral differentiation mat...

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...
