量子引力中的代数结构

Algebraic structures in quantum gravity

Adrian Tanasa

摘要:

从最近介绍的自旋泡沫模型的代数结构,我们定义了一个Hopf代数除以适当的商。这样定义的结构,自然允许从组合的角度用量子场论对自旋泡沫模型进行镜像分析。一个嫁接算子的引入允许等效的戴森-Schwinger方程被写入。非平凡的例子明确制定。最后讨论了结果的物理意义。

英文摘要:

Starting from a recently-introduced algebraic structure on spin foam models, we define a Hopf algebra by dividing with an appropriate quotient. The structure, thus defined, naturally allows for a mirror analysis of spin foam models with quantum field theory, from a combinatorial point of view. A grafting operator is introduced allowing for the equivalent of a Dyson-Schwinger equation to be written. Non-trivial examples are explicitly worked out. Finally, the physical significance of the results is discussed.
