Abstract :
In the recent years spectral methods are used for solving sti® and non-sti® partial di®er- ential equations and ordinary di®erential equations. Various types of spectral methods for steady and unsteady problems are proposed to solve sti® and non-sti® partial di®erential equa- tions e±ciently. In this article some schemes for solving sti® partial di®erential equations are derived. There are twofold: ¯rst method is based on Chebyshev polynomials for solving high- order boundary value problems. Second methods are based on Fourier-Galerkin and collocation spectral methods in space and Runge-Kutta, exponential time di®erencing, Taylor expansion and contour integral in time for solving sti® PDEs. Numerical results show the e±ciency of proposed schemes.
