The Ekman flow and related problems: spectral theory and numerical analysis
Leon A. Greenberg, Marco Marletta · Mathematical Proceedings of the Cambridge Philosophical Society · 2004
We consider singular block operator problems of the type arising in the study of stability of the Ekman boundary layer. The essential spectrum is located, and an analysis of the . This, in turn, permits a rigorous analysis of the convergence of approximations to the spectrum arising from regular problems. Numerical results illustrate the theory.
