具有有限个连通Feynman图的拓扑场论

A Topological Field Theory With a Finite Number of Connected Feynman Diagrams

Franco Ferrari

摘要:

构造了一种新的拓扑场论,它的特征是类似于非交换的Chern-Simons场论的立方相互作用,但仍保留了交换情形的简单性.这个理论的微扰展开实际上只包含两个连通的费曼图,即传播子和一个三顶点。除了高斯链接数,威尔逊圈振幅产生进一步的拓扑不变量,其物理和数学意义进行了研究。

英文摘要:

A new topological field theory is constructed, which is characterized by cubic interactions similar to those of non-abelian Chern-Simons field theories, but still retains the simplicity of the abelian case. The perturbative expansion of this theory contains in fact only two connected Feynman diagrams, the propagator and a three vertex. Apart from the Gauss linking number, the Wilson loop amplitudes generate a further topological invariant, whose physical and mathematical meaning is investigated.
