讨论了傅里叶和广义拉盖尔函数的混合谱方法,建立了针对二维外部问题的混合谱格式,数值结果说明了这种方法的有效性。
This paper is devoted to the applications of a mixed spectral method for a two - dimensional exterior problem, using Fourier and generalized Laguerre functions. We consider a nonlinear strongly damped wave equation. A mixed spectral scheme is proposed. Numerical results demonstrate the efficiency of this new approach.
