Nonlinear Aspects of the Renormalization Group Flows of Dyson's Hierarchical Model
Y. Meurice
We review recent results concerning the renormalization group (RG) transformation of Dyson's hierarchical model (HM). This model can be seen as an approximation of a scalar field t…
Universal Crossover in Perturbation Theory with a Large Field Cutoff
L. Li, Y. Meurice
For lambda phi^4 models, the introduction of a large field cutoff improves significantly the accuracy that can be reached with perturbative series but the calculation of the modifi…
Non-Perturbative Aspects of Scalar Field theory
Y. Meurice, S. Niermann, G. Ordaz
Using the hierarchical approximation, we discuss the cut-off dependence of the renormalized quantities of a scalar field theory. The naturalness problem and questions related to tr…
A Perturbative Improvement of the Hierarchical Approximation
Yannick Meurice
We propose a perturbative improvement of the hierarchical approximation for gaussian models. The procedure is based on a relabeling of the momenta which allows one to express the s…
