Spectral and Pseudospectral Approximations in Time for Parabolic Equations

Author(s)

Abstract

In this paper, spectral and pseudospectral methods are applied to both time and space variables for parabolic equations. Spectral and pseudospectral schemes are given, and error estimates are obtained for approximate solutions.

Keywords:

Spectral approximation pseudospectral approximation parabolic equation error estimate.
