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 k. The situation with gauge dependence is similar to the standard formulation based on the effective one-particle irreducible average action.

泛函化正规化群的替代流动方程的量表依赖性
研究了功能重整化群替代流方程的尺度依赖问题。结果表明,有效的两粒子不可约有效作用取决于在IR参数k的任何值下的量规。具有轨距依赖性的情况类似于基于有效的单粒子不可约平均作用的标准公式。
