论文摘要
量子场理论计算所需的最重要的数学工具之一是场传播器。应用程序总是以平面波的形式进行的，尽管这已经提供了许多宏伟的结果，但仍然可以允许人们怀疑可以写入最通用的传播器的形式是什么。在本文中，通过利用所谓的极性形式，我们发现了旋转器中最通用的传播器，无论是规则还是单数，并且在向量的情况下进行了一般讨论。
One of the most important mathematical tools necessary for Quantum Field Theory calculations is the field propagator. Applications are always done in terms of plane waves and although this has furnished many magnificent results, one may still be allowed to wonder what is the form of the most general propagator that can be written. In the present paper, by exploiting what is called polar form, we find the most general propagator in the case of spinors, whether regular or singular, and we give a general discussion in the case of vectors.
