On the Chebyshev-tau approximation for some singularly perturbed two point boundary value problems – Numerical experiments


In this paper we are concerned with numerical stability of Chebyshev-tau method in solving some singularly perturbed two-point boundary value problems.

We consider linear as well as nonlinear (convection-dominated flow) problems. In order to avoid the lack of numerical stability of this method we try a smoothing technique as well as a domain decomposition for linear problems.

Some successful numerical experiments are carried out.
