Eigenfunction expansions and scattering theory associated with Dirac equation
Lev Sakhnovich
The classical Lippmann-Schwinger equation (LS equation) plays an important role in the scattering theory for the non-relativistic case (Schrödinger equation). In our previous paper…

A new approach to divergences in quantum electrodynamics, concrete examples
Lev Sakhnovich
We consider the divergences in quantum electrodynamics. Our approach is based on ideas from the theory of generalized wave operators. In particular, we use the concept of the devia…

Operator Bezoutiant and Roots of Entire Functions, Concrete Examples
L. A. Sakhnovich
In this paper we use the Bezoutiant method to describe the conditions under which two entire functions have not common roots. We apply the general results to concrete examples. In…
