二维外部问题的混合谱方法(英文)
Mixed spectral method for 2-D exterior problem
【摘要】 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.
【Abstract】 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.
