关于Dirac方程的Feynman路径积分的注记

Notes on the Feynman path integral for the Dirac equation

Wataru Ichinose

摘要:

本文是作者前一篇文章的继续。在前一篇文章中,作者严格地构造了狄拉克方程的费曼路径积分,它是满足叠加原理的,对时空中一个电子在任意方向上以任意速度、在时间上以有限圈数向前和向后运动的所有路径的历史求和。本文首先推广了前一篇文章的结果,然后用直接的方法证明了我们的Feynman路径积分满足么正性原理和因果性原理。

英文摘要:

This paper is a continuation of the author's preceding one. In the preceding paper the author has rigorously constructed the Feynman path integral for the Dirac equation in the form of the sum-over-histories, satisfying the superposition principle, over all paths of one electron in space-time that goes in any direction at any speed, forward and backward in time with a finite number of turns. In the present paper, first we will generalize the results in the preceding paper and secondly prove in a direct way that our Feynman path integral satisfies the unitarity principle and the causality one.
