Friedel formula and Krein's theorem in complex potential scattering theory
arXiv:2202.12465
Abstract
In this work, the generalization of Friedel formula and Krein's theorem in complex potential scattering theory is presented. The consequence of various symmetry constraints on dynamical system are discussed. In addition, Muskhelishvili-Omnès representation of Krein's theorem is also given and discussed.
