Perturbation theory and renormalization group equations
Renormalization group ~RG! methods are an essential ingredient in the study of nonperturbative problems in continuum and lattice formulations of quantum field theory. A number of RG equations have been proposed, where the starting point is the ~infrared! regularized one-loop effective action. Taking the derivative with respect to the infrared scale together with a subsequent one-loop improvemen...
متن کاملRenormalization-Group-improved perturbation theory
A method for computing the low-energy non-perturbative properties of SUSY GFT, starting from the microscopic lagrangian model, is presented. The method relies on covariant SUSY Feynman graph techniques, adapted to low energy, and RenormalizationGroup-improved perturbation theory. We apply the method to calculate the glueball superpotential in N = 1 SU(2) SYM and obtain a potential of the Venezi...
متن کاملRenormalization group method and canonical perturbation theory
Abstract. Renormalization group method is one of the most powerful tool to obtain approximate solutions to differential equations. We apply the renormalization group method to Hamiltonian systems whose integrable parts linearly depend on action variables. We show that the renormalization group method gives the same approximate solutions as canonical perturbation theory up to the second order of...
متن کاملPerturbation theory and renormalisation group equations
Renormalisation group (RG) methods are an essential ingredient in the study of non-perturbative problems in continuum and lattice formulations of quantum field theory. A number of RG equations have been proposed, where the starting point is the (infrared) regularised one loop effective action. Taking the derivative w.r.t. the infrared scale together with a subsequent one loop improvement leads ...
متن کاملPerturbation Theory and the Renormalization Group in Genetic Dynamics
Although much progress has been made in recent years in the theory of GAs and GP, there is still a conspicuous lack of tools with which to derive systematic, approximate solutions to their dynamics. In this article we propose and study perturbation theory as a potential tool to fill this gap. We concentrate mainly on selection-mutation systems, showing different implementations of the perturbat...
