Abstract

A new, more exact exposition of Bogoliubov's theory of R-operation, which is of great importance in the quantum theory of field, is given in this paper. A definition of R-operation is contained in §§3 and 5. Theorem 2, confirming the possibility of writing down the contribution from any Feinman diagram after applying R-operation to it in the form of (8. 3), is the basic one. The final result consists in the proof of the limiting ratio (9 4).
