The renormalized $ϕ_{4}^{4}$ -trajectory by perturbation theory in a running coupling using partial differential equations

Abstract

We compute the renormalized trajectory of $ϕ_{4}^{4}$ -theory by perturbation theory in a running coupling. We use an exact infinitesimal renormalization group. The expansion is put into a form which is manifestly independent of the scale parameter.
