论文摘要
我们证明了重新归一化组转换的整合步骤保留了有效作用的准级数。这在圆环上的单个,真实的标量字段中显示了这一点,但是证明更普遍地保持。可以将主要结果视为显示了Polchinski方程产生的流量下的准分子子集的流量不变性。
We demonstrate that the integration-out step of the renormalization group transformation preserves the quasilocality of the effective action. This is shown in the case of a single, real, scalar field on a torus, but the proof holds more generally. The main result can be thought of as showing the flow invariance of the quasilocal subset under the flow generated by the Polchinski equation.
