An asymptotic expression for the vertex function in the region of large momenta in quantum electrodynamics is investigated in the ladder approximation. To formulate a calculational model in the ladder approximation, an iterative scheme has been used

A method of calculating the forward scattering amplitude for fermions and scalar bosons with the exchange of scalar particle is suggested. The Bethe-Salpeter ladder equation for the imaginary part of the amplitude is constructed and a solution in Reg

The Dirac method of canonical quantization of theories with second class constraints has to be modified if the constraints depend on time explicitly. A solution of the problem was given by Gitman and Tyutin. In the present work we propose an independ
