Abstract

We consider the spectral interpolation error for both Chebyshev pseudo-spectral and Galerkin approximations. We develop a family of functionals Ir(u), with the property that the maximum norm of the error is bounded by Ir(u)/Jr, where r is an integer and J is the degree of the polynomial approximation. These functionals are used in an adaptive procedure whereby the problem is dynamically transformed to minimize Ir(u). The number of collocation points is then chosen to maintain a prescribed error bound. The method is illustrated by various examples from combustion problems in one and two dimensions.
