Abstract:
A method for calculating the $\beta$-function and anomalous dimensions, convenient for numerical calculations in the $\varepsilon$-expansion framework, was previously proposed, and the relation underlying the method was verified up to the four-loop approximation. We prove this relation in all orders of the perturbation theory.
Keywords:
renormalization group, $\varepsilon$-expansion, multiloop diagram, critical exponent.
