算子正则化下弯曲时空中的几何$β$ -函数

The geometric $β$-function in curved space-time under operator regularization

Susama Agarwala

摘要:

在本文中,我比较了重整化群流的生成元,或几何$β$ -函数的维数正则化和算子正则化。然后,我扩展的分析表明,几何$β$ -函数的标量场理论封闭紧凑的黎曼流形上定义的整个流形。然后,我扩展的分析,找到发电机的重整化群流的共形标量场理论相同的流形。在这种情况下,几何$β$函数没有定义。

英文摘要:

In this paper, I compare the generators of the renormalization group flow, or the geometric $β$-functions for dimensional regularization and operator regularization. I then extend the analysis to show that the geometric $β$-function for a scalar field theory on a closed compact Riemannian manifold is defined on the entire manifold. I then extend the analysis to find the generator of the renormalization group flow for a conformal scalar-field theories on the same manifolds. The geometric $β$-function in this case is not defined.
