Based on the idea of quasi-interpolation and radial basis functions approximation, a numerical method is developed to quasi-interpolate the forcing term of di erential equations by using radial basis functions. A highly accurate approximation for the solution can then be obtained by solving the corr
A conservative spectral method is proposed to solve several two-dimensional nonlinear wave equations. The conventional fast Fourier transform is used to approximate the spatial derivatives and a three-level difference scheme with a free parameter ΞΈ is to advance the solution in time. Our time discre
