Physical Problems Solved by the Phase-Integral Method

Description This book covers one of the most efficient approximation methods for the theoretical analysis and solution of problems in theoretical physics and applied mathematics. The method can be applied to any field involving second order ordinary differential equations. It is written with practical needs in mind, with 50 solved problems covering a broad range of subjects and making clear which concepts and results of the general theory are needed in each case. Contains 50 problems with solutions, to illustrate the practical applications of the theory Authors are leading figures in the field
