Abstract

A divergent perturbative expansion resummation method is proposed for quantum electro-dynamics and related field theories. It is based on nonlinear sequence transformation which used data of a finite number of perturbative coefficients. Results show that nonlinear sequence transformation predictions is much superior and accurate than predictions obtained using Pade approximants method.
