A Resummable beta-Function for Massless QED
Oliver J. Rosten
Within the set of schemes defined by generalized, manifestly gauge invariant exact renormalization groups for QED, it is argued that the beta-function in the four dimensional massl…
A Comment on the Path Integral Approach to Cosmological Perturbation Theory
Oliver J. Rosten
It is pointed out that the exact renormalization group approach to cosmological perturbation theory, proposed in Matarrese and Pietroni, JCAP 0706 (2007) 026, arXiv:astro-ph/070356…
Sensitivity of Nonrenormalizable Trajectories to the Bare Scale
Oliver J. Rosten
Working in scalar field theory, we consider RG trajectories which correspond to nonrenormalizable theories, in the Wilsonian sense. An interesting question to ask of such trajector…
Universality From Very General Nonperturbative Flow Equations in QCD
Oliver J. Rosten
In the context of very general exact renormalization groups, it will be shown that, given a vertex expansion of the Wilsonian effective action, remarkable progress can be made with…
The Gauge Invariant ERG
Oliver J. Rosten, Tim R. Morris, Stefano Arnone
We sketch the construction of a gauge invariant Exact Renormalization Group (ERG). Starting from Polchinski's equation, the emphasis is on how a series of ideas have combined to yi…
