Corrections to the asymptotic expressions for the higher orders of perturbation theory

Yu. A. Kubyshin


Abstract: A technique is developed for calculating the corrections in $1/n$ to the asymptotic expression for the $n$-th term of the perturbation series for the example of the scalar massless model $\varphi_{(4)}^4$ with internal symmetry $O(N)$. The first correction for the $\beta$ function is obtained.
