论文摘要
研究了功能重新归一化组中有效平均作用的量规依赖性。有效的平均作用被认为是流动方程的非扰动解，这是该方法的基本方程。事实证明，在任何规模的IR截止范围内，有效的平均作用取决于仪表，这使得对此方法的所有获得的结果都无法进行物理解释。
The gauge dependence of effective average action in the functional renormalization group is studied. The effective average action is considered as non-perturbative solution to the flow equation which is the basic equation of the method. It is proven that at any scale of IR cutoff the effective average action depends on gauges making impossible physical interpretation of all obtained results in this method.
