چکیده
Gradient Flow Exact Renormalization Group (GFERG) is a framework to define the Wilson action via gradient flow equation. We study fixed point structure of GFERG equation associated with general for scalar field theories and show that it same as conventional Wilson-Polchinski (WP) in general. Furthermore, we discuss has similar RG around WP illustrate these results $O(N)$ non-linear sigma model $4-\epsilon$ dimensions Wilson-Fisher point.

Exact Renormalization Group Approach in Scalar and Fermionic Theories
As it is known (see an interesting review by Shirkov) the basic idea of the renormalization group (RG) was formulated in an article by Stueckelberg and Petermann. The existence of such group of transformations was related to the arbitrariness in the procedure of subtraction of ultraviolet divergencies in quantum electrodynamics. Functional equations for the propagators in the ultraviolet limit,...
متن کاملField Strength Correlator and an Infrared Fixed Point of the Wilsonian Exact Renormalization Group Equations
The correlator of two field strengths is computed from an effective action for Yang Mills theories, which contains both gluons and an auxiliary antisymmetric tensor field for the field strength as local variables. This action allows to relate explicitly many different approaches to confinement, and is computed using Wilsonian renormalization group equations with the bare Yang Mills action as st...
متن کاملExact renormalization group study of fermionic theories
The exact renormalization group approach (ERG) is developed for the case of pure fermionic theories by deriving a Grassmann version of the ERG equation and applying it to the study of fixed point solutions and critical exponents of the two-dimensional chiral Gross-Neveu model. An approximation based on the derivative expansion and a further truncation in the number of fields is used. Two soluti...
متن کاملRenormalization group equations for effective field theories
We derive the renormalization group equations for a generic nonrenormalizable theory. We show that the equations allow one to derive the structure of the leading divergences at any loop order in terms of one-loop diagrams only. In chiral perturbation theory, e.g., this means that one can obtain the series of leading chiral logs by calculating only one loop diagrams. We discuss also the renormal...
متن کاملRenormalization Group Analysis of Scalar Field
We employ Wilson's renormalization group procedure in an attempt to classify and understand the physics of the continuum limits of scalar field theories. Analysis of the flows near the Gaussian fixed point reveals the existence of an infinite set of asymptotically free continuum limits. We study the associated physics by calculating scattering cross sections and the i-loop effective potential. ...
