Title: ASYMPTOTIC SOLUTION OF EIGENVALUE PROBLEMS

Abstract

A method is presented for the constrnction of asymptotic formulas for the large eigenvalues and the corresponding eigenfunctions of boundary value problems for partial differential equations. It is an adaptation to bounded domains of the method previously devised to deduce the corrected Bohr-Sommerfeld quantum conditions. When applied to the reduced wave equation in various domains for which the exact solutions are known, it yields precisely the asymptotic forms of those solutions. It was applied to an arbitrary convex plane domain for which the exact solutions are not known. Two types of solutions were found, called the "whispering gallery" and "bouncing ball" modes. Applications were made to the Schroedinger equation. (auth)
