一类非线性抛物型方程的大时间Chebyshev拟谱逼近

Large Time Chebyshev Pseudo Spectral Approximations of A Kind of Nonlinear Parabolic Equations

运用Ｃｈｅｂｙｓｈｅｖ 拟谱方法考虑一类非线性抛物方程的大时间问题，建立半离散的拟谱格式。

Studies the large time problems of a kind of nonlinear parabolic equations, constructs semidiscrete spectral approximations, and gets the error estimate that holds uniformly on the interval 0≤t≤+∞.
