重整化群的运算构造

Operadic construction of the renormalization group

Jean-Louis Loday, Nikolay M. Nikolov

摘要:

首先,我们给出了一个与对称操作数相关联的群的函子结构。应用于自同态运算,它给出了形式自同态群。其次,我们关联到任何家庭的装饰图的收缩稳定的对称操作。在量子场论模型的情况下,它给出了重整化群。作为一个例子,我们得到了一个操作性的解释组的“congraphisms”连接到Connes-Kreimer Hopf代数。

英文摘要:

First, we give a functorial construction of a group associated to a symmetric operad. Applied to the endomorphism operad it gives the group of formal diffeomorphisms. Second, we associate a symmetric operad to any family of decorated graphs stable by contraction. In the case of Quantum Field Theory models it gives the renormalization group. As an example we get an operadic interpretation of the group of "diffeographisms" attached to the Connes-Kreimer Hopf algebra.
