Hamilton-Jacobi Equation and the Tree Formula for Proper Vertices

Christian Wieczerkowski

The tree formula, which relates proper and connected vertices, is shown to be the solution to a Hamilton-Jacobi equation.

Rigorous control of the non-perturbative corrections to the double expansion in $g$ and $g^{2} ln (g)$ for the $ϕ_{3}^{4}$ -trajectory in the hierarchical approximation

Christian Wieczerkowski

We study the renormalization invariant trajectory of the $ϕ^{4}$ -perturbation of the free field fixed point in the hierarchical approximation. We parametrize it by a running $ϕ^{4}$ -co…
