Renormalization group and the ladder approximation in field theory

K. G. Klimenko


Abstract: For the example of the field theory ${\lambda\varphi_6}^3$, a renormalized equation is obtained for the mass operator in the ladder (rainbow) approximation. The Gell-Mann–Low functions and the anomalous dimension are calculated in the same approximation.
