A new, exact, gauge-invariant RG-flow equation
We introduce a scale-dependent effective action defined through a partial Legendre transform first discussed by Zumino more than 30 years ago. This new effective action depends, at any scale, on all degrees of freedom, is gauge-invariant/general-covariant, and obeys a simple, exact and manifestly ga...
