The concepts and methods of the quantum field theory are applied to the many-electron problem in atoms and molecules. The field-theoretic formulation of perturbation theory is developed in these problems with respect to the smallness of the mutual interaction of the electrons and rules are given for composing the corresponding Feynman diagrams and the contributions from them. A comparison is made in the first and second orders between the field-theoretic and conventional forms of the perturbation theory. Two systems of exact field equations are formulated one system of field equations, the Dyson-Schwinger, for study of the one-particle corpuscular aspect of the problem, and another, new system of field equations for study of the two-particle corpuscular aspect of the problem.
