An asymptotic-numerical method for a time-dependent singularly perturbed system with turning points. (English) Zbl 0859.65099
The authors use asymptotic analysis to suggest a domain decomposition method to solve a time-dependent singularly perturbed system with turning points. In different subdomains they use different approximating equations and numerical methods to produce an accurate and efficient numerical method.
