Weyl's theory for a set of N ‐coupled singular second‐order differential equations is analyzed in relation to S ‐matrix theory and a dilated version is presented. Applications of this theory to two single channel scattering model problems and a two‐channel model problem are given. Some implications of the present theory are discussed.
