论文摘要
我们研究功能重归其化组（FRG）的较高衍生化延伸。我们考虑标量场的FRG方程，该方程由具有有效动作和任意截止函数的较高功能衍生物组成的术语组成。我们表明，Wilson-Fisher固定点周围的Epsilon扩展确实是由FRG方程的局部电位近似复制的。
We study higher derivative extension of the functional renormalization group (FRG). We consider FRG equations for a scalar field that consist of terms with higher functional derivatives of the effective action and arbitrary cutoff functions. We show that the epsilon expansion around the Wilson-Fisher fixed point is indeed reproduced by the local potential approximation of the FRG equations.
