1864-5879 ion of the laws of nature from contingent boundary or initial conditions, which has become part of our physical intuition, is both based on and expressed in the properties of solutions of differential equations. Within these equations we make a further distinction: that between what in mechanics are

Faddeev’s Solution weighted .-spaces (on which the Laplacian is not essentially self-adjoint). The Green’s function (1.4) is one member of this family. There is a variety of ways of approaching these Green’s functions, but we shall do so by an avenue originally used by Faddeev.

The Direct Scattering ProblemR, is not assumed to have any particular symmetry properties but it is assumed to decrease to zero at infinity in a manner to be specified later. The solution is to describe a plane wave sent in the direction of the unit vector . toward the “scattering center,” together with an outgoing spherical wa

The Inverse Problemnfer the underlying potential in the Schrodinger equation (1.1). It should be noted that from a physical point of view the experimental data are, at best, given by the differential scattering cross section ∣.∣. rather than the complex scattering amplitude itself. There is, therefore, a first step in

The Regular Solutiona point. Such a solution is necessarily an entire analytic function of . of exponential type |.|. It is this property that is exploited in the solution technique of the inverse spectral problem due to Gel’fand and Levitan.

The Inverse Probleming to be solved is an inverse spectral problem posed for the regular solution. This inverse spectral problem is of relatively little intrinsic interest because in dimensions higher than one (for noncentral potentials) the regular solution is not a natural solution of the Schrodinger equation. As we
