Gauge dependence of alternative flow equation for the functional renormalization group

Abstract
The gauge dependence problem of alternative flow equation for the functional renormalization group is studied. It is shown that the effective two-particle irreducible effective action depends on gauges at any value of IR parameter . The situation with gauge dependence is similar to the standard formulation based on the effective one-particle irreducible effective action.
