关于重整化群特征的微分方程

On the Differential equations of the characters for the Renormalization group

Masato Sakakibara

摘要:

由于Connes-Kreimer重整化理论与可积系统的相似性,我们导出了重整化特征$ϕ_+$和反项$ϕ_-$的单位质量微分方程.给出了$ϕ_-$散射型公式的另一种证明.给出了${\mathbb P}^1$上坐标反项的微分方程。重整化群的族被定义为可积系统。

英文摘要:

Owing to the analogy between the Connes-Kreimer theory of the renormalization and the integrable systems, we derive the differential equations of the unit mass for the renormalized character $ϕ_+$ and the counter term $ϕ_-$. We give another proof for the scattering type formula of $ϕ_-$. The differential equation of the counter term of coordinate on ${\mathbb P}^1$ is also given. The hierarchy of the renormalization groups is defined as the integrable systems.
