The renormalized $ϕ^4_4$-trajectory by perturbation theory in a running coupling using partial differential equations
Abstract
Description
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.
