规范理论的重整化与图的Hopf代数

Renormalization of Gauge theories and the Hopf Algebra of Diagrams

D. V. Prokhorenko

摘要:

1999年A. Connes和D. Kreimer在标量场理论的Feynman图上发现了一种Hopf代数结构。他们发现重整化可以解释为解决一些黎曼-希尔伯特问题。在这项工作中,他们的计划推广到非交换规范理论的情况下提出的。定义了规范群在Hopf代数上的作用,并证明了该作用与Hopf代数结构是一致的。给出了S-矩阵的一种新的证明方法。

英文摘要:

In 1999 A. Connes and D. Kreimer have discovered a Hopf algebra structure on the Feynman graphs of scalar field theory. They have found that the renormalization can be interpreted as a solving of some Riemann - Hilbert problem. In this work the generalization of their scheme to the case of nonabelian gauge theories is proposed. The action of the gauge group on the Hopf algebra is defined and the proof that this action is in consistent with the Hopf algebra structure is given. The scetch of new proof of S-matrix, based on the Hopf algebra is given.
