狄拉克伽玛方程、经典规范场和Clifford代数

Dirac gamma-equation, classical gauge fields and Clifford algebra

N. G. Marchuk

摘要:

借助与Clifford代数有关的数学工具,引入了一个方程,我们称之为Dirac伽玛方程。该方程可以看作是电子Dirac方程的推广,并研究了Dirac γ方程的一些性质(平面波、流、正则型)。进而,在关于幺正群的定域规范不变性的基础上,引入了Dirac伽玛方程和Yang-Mills方程组或麦克斯韦方程组组成的方程组。这个方程组描述了狄拉克场与杨-米尔斯或麦克斯韦规范场的相互作用。这个系统的方程的特点进行了研究,为各种规范群和经典规范场的新的和标准的建设之间的联系进行了讨论。

英文摘要:

An equation, we call Dirac gamma-equation, is introduced with the help of the mathematical tools connected with the Clifford algebra. This equation can be considered as a generalization of the Dirac equation for the electron. Some features of Dirac gamma- equation are investigated (plane waves, currents, canonical forms). Furthermore, on the basis of local gauge invariance regarding unitary group, a system of equations is introduced consisting of Dirac gamma-equation and the Yang-Mills or Maxwell equations. This system of equations describes a Dirac's field interacting with the Yang-Mills or Maxwell gauge field. Characteristics of this system of equations are studied for various gauge groups and the liaison between the new and the standard constructions of classical gauge fields is discussed.
