Algebraization of the perturbation theory in quantum chromodynamics
Turbiner A. V.
It is shown that if an unperturbed problem is a multidimensional harmonic oscillator or a hydrogen-like system and the perturbation is a polynomial, then the formulation of perturbation theory must be a purely algebraic problem. A hydrogen-like system in an electric field W parallel to the magnetic field ^^is analyzed. The correction to the ground-state energy of order $2 ßÐÊö2 is calculated. Some structures of the arbitrary "correction to the wave function" are determined in the explicit form.
