Description
A dynamic scheme based on the equation for the T-matrix transfer momentum spectral density and integral representation for the Jost function (matrix) is proposed for the Schroedinger and Dirac hamiltonians in arbitrary N-dimension spaces with local and nonlocal Yukawa potential and model with N couples channels. A generalization of the off-shell Jost function method for these hamiltonians and universal renormalization procedure of the Jost function calculation for singular and nonlocal potentials are proposed
