Triviality in a Non-Perturbative Second-Order Mean-Field Theory for $ϕ_{4}^{4}$

Majdouline Borji

We introduce a second-order mean-field description of the four-dimensional Euclidean $ϕ^{4}$ model within the Wilson--Polchinski renormalization-group framework. The construction is…

Perturbative renormalization of the lattice regularized $ϕ_{4}^{4}$ with flow equations

Majdouline Borji, Christoph Kopper

The flow equations of the renormalization group allow to analyse the perturbative $n$ -point functions of renormalizable quantum filed theories. Rigorous bounds implying renormaliza…
