On Time-Splitting Pseudospectral Discretization for Nonlinear Klein-Gordon Equation in Nonrelativistic Limit Regime
《Communications in Computational Physics》2014年第7期440-466,共27页Xuanchun Dong Zhiguo Xu Xiaofei Zhao 
supported by the Singapore A*STAR SERC PSF-Grant 1321202067。
In this work,we are concerned with a time-splitting Fourier pseudospectral(TSFP)discretization for the Klein-Gordon(KG)equation,involving a dimensionless parameterε∈(0,1].In the nonrelativistic limit regime,the smal...

Truncated Gaussian RBF Differences are Always Inferior to Finite Differences of the Same Stencil Width被引量:1
《Communications in Computational Physics》2009年第1期42-60,共19页John P.Boyd Lei Wang 
Radial basis functions(RBFs)can be used to approximate derivatives and solve differential equations in several ways.Here,we compare one important scheme to ordinary finite differences by a mixture of numerical experim...
