On the Renormalization Group Transformation for Scalar Hierarchical Models
نویسندگان
چکیده
We give a new proof for the existence of a non{Gaussian hierarchical renormalization group xed point, using what could be called a beta{function for this problem. We also discuss the asymptotic behavior of this xed point, and the connection between the hierarchical models of Dyson and Gallavotti. 1 Supported in Part by the National Science Foundation under Grant No. DMS{8802590. 2 Supported in Part by the Swiss National Science Foundation.

Optimization of Renormalization Group Transformations
This thesis examines the optimization of renormaiization group transformations. To do this I have examined simple spin models where some understanding of the problems which arise and particularly the systematic errors can be acquired. In the first chapter I have given a brief description of critical phenomena which provides the motivation for the study of the renormalization group in this rest ...
متن کاملNonlinear Aspects of the Renormalization Group Flows of Dyson’s Hierarchical Model
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 theory on a lattice. We introduce the HM and show that its large group of symmetry simplifies drastically the blockspinning procedure. Several equivalent forms of the recursion formula are presented with unified notati...
متن کاملNon-Perturbative Fine-Tuning in Approximately Supersymmetric Models
We present two Fermi-Bose models with an approximate supersymmetry and which can be solved numerically with great accuracy using the renormalization group method. The bosonic parts of these models consist in Dyson’s hierarchical model with one and two scalar components respectively. We discuss the question of the perturbative cancellations of divergences and compare with the non-perturbative fi...
متن کاملRemarks Concerning Polyakov’s Conjecture for the 3D Ising Model and the Hierarchical Approximation
We consider the possibility of using the hierarchical approximation to understand the continuum limit of a reformulation of the 3D Ising model initiated by Polyakov. We introduce several new formulations of the hierarchical model using dual or fermionic variables. We discuss several aspects of the renormalization group transformation in terms of these new variables. We mention a reformulation o...
متن کاملCORE Technology and Exact Hamiltonian Real-Space Renormalization Group Transformations
The COntractor REnormalization group (CORE) method, a new approach to solving Hamiltonian lattice systems, is presented. The method defines a systematic and nonperturbative means of implementing KadanoffWilson real-space renormalization group transformations using cluster expansion and contraction techniques. We illustrate the approach and demonstrate its effectiveness using scalar field theory...
