Abstract : Newman and Thorson have recently proposed and developed a new method for the rapid and efficient solution of eigenvalue problems associated with a linear second order differential equation. Results on the application of the method to obtain the solution of Stoke's equation, the evaluation of the eigenvalue spectrum for a parabolic and Williams-Horne profile in an infinite ocean, and the solutions and eigenvalues in a semi-infinite ocean described by a positive linear gradient profile are presented.
