Four-loop approximation in the$\varphi^4$model
Abstract
The results are given of calculations of the Gelt-Mann–Low function in the four-loop
approximation in the massless model with quartic interaction. The coefficients in the
expansion of the Gell-Mann–Low function calculated in the framework of perturbation
theory are compared with the coefficients calculated in accordance with the asymptotic
formula.
