ON AN APPLICATION OF THE OPERATORS OF CRUMM-ICAEIN TO THE DECOMPOSITION IN PRODUCTS OF THE SOLUTIONS OF TWO EQUATIONS OF SCHRODINGER WITH EQUAL SPECTRA

Abstract

There are considered expansions over products of solutions of two Schrödinger equations on semi-axis with Dirichlet boundary conditions when discrete spectra coincide. We constructed by the Crumm-Krein transformations the analogous formulae for the expansions when there are one more or less eigenvalues.
