Abstract
We show that the Schwarz alternating procedure offers a good algorithm for the numerical solution of singular perturbation problems, provide d the domain decomposition is properly designed to resolve the boundar y and transition layers. We give sharp estimates for the optimal posit ion of the domain boundaries and study the convergence rates of the al gorithm for various linear second-order singular perturbation problems . We report on implementation results for a turning-point problem and a combustion problem.
