Functional Renormalization Group Flows and Gauge Consistency in QED
Yoshio Echigo, Yuji Igarashi, Katsumi Itoh +2
We consider quantum electrodynamics with chiral four-Fermi interactions in the functional renormalization group approach. In gauge theories, the functional flow equation for the ef…

Realization of Chiral Symmetry in the ERG
Yoshio Echigo, Yuji Igarashi
We discuss within the framework of the ERG how chiral symmetry is realized in a linear model. A generalized Ginsparg-Wilson relation is obtained from the Ward-Takahashi identit…
