LEGENDRE SPECTRAL COLLOCATION METHOD FOR SECOND-ORDER NONLINEAR ORDINARY/PARTIAL DIFFERENTIAL EQUATIONS

摘要

We propose an efficient Legendre-Gauss collocation algorithm for second-order nonlinear ordinary differential equations (ODEs). We also design a Legendre-Gauss-type collocation algorithm for time-dependent second-order nonlinear partial differential equations (PDEs), which can be implemented in a synchronous parallel fashion. Numerical results indicate the high accuracy and effectiveness of the suggested algorithms.
