The method of variational matrix Pade approximants is seen to unify the Green's function method and the variational principle for calculating scattering amplitudes. The surprising result that exact answers can be obtained for square well potentials is thereby proved, and the remarkable accuracy of t

The continuous fraction expression of a partial-wave matrix element following from the distortion operator method developed before is proved to be an s-fraction expansion of the matrix element. The proof is more general, it applies to an arbitrary matrix element of T or K operator. One of our former

The aim of this paper is to define vector Pade -type approximants and vector Pade approximants following the same ideas as in the scalar case. This approach will be possible using Clifford's algebra structures. Vector Pade approximants will be derived from the theory of formal vector orthogonal poly
