摘要
Inverse scattering theory is extended to one-dimensional Schrodinger problems with near-boundary singularities of the form v(z -> 0)similar or equal to-z(-2/4) + v(-1) z(-1). Trace formulae relating the boundary value v0 of the nonsingular part of the potential to spectral data are derived. Their potential is illustrated by applying them to a number of Schrodinger problems with singular potentials.
