This is a very brief introduction to Wilson’s Renormalization Group with emphasis on mathematical developments.
متن کاملExact Renormalization Group with Fermions
The set of ideas enclosed in the Renormalization Group (RG, hereafter) has led to a variety of developments in many fields, as this Conference has made apparent. From a particle theorist point of view they englobe a bunch of ideas form which we may understand what a quantum field theory is. Moreover, it provides a framework for nonperturbative calculations. In recent years, there has been an in...
متن کاملTwo-loop β-function from the exact renormalization group
We calculate the two-loop renormalization group (RG) β-function of a massless scalar field theory from the irreducible version of Polchinski’s exact RG flow equation. To obtain the correct two-loop result within this method, it is necessary to take the full momentum-dependence of the irreducible four-point vertex and the six-point vertex into account. Although the same calculation within the or...
متن کاملExact Tachyon Potential from the Wilsonian Renormalization Group
The derivative expansion of the Wilsonian renormalization group generates additional terms in the effective β-functions not present in the perturbative approach. Applied to the nonlinear σ model, to lowest order the vanishing of the β-function for the tachyon field generates an equation analogous to that found in open string field theory. Although the nonlinear term depends on the cut-off funct...
