守恒Noether流、Utiyama不变变分理论和局域规范不变性中的速度依赖性

Conserved Noether Currents, Utiyama's Theory of Invariant Variation, and Velocity Dependence in Local Gauge Invariance

György Darvas

摘要:

本文讨论了导出变量在规范场中应用的数学后果。物理学知道几种现象,它们首先取决于速度(例如,电荷在磁场中运动所产生的力,或洛伦兹变换)。本文利用Noether第二定理允许广义变量的性质,推广了Al-Kuwari和Taha(1991)的文章,得到了一个新的结论。他们的结论是,没有额外的守恒电流与局部规范不变性有关。我们表明,在更一般的情况下,有进一步保守的诺特电流。在它的方法中,本文在依赖于速度空间坐标的规范场的存在下,重建了Utiyama(1956,1959)引入的线索,以及Al-Kuwari和Taha(1991)的线索。在这门课中,我们运用了与米尔斯(Mills,1989)的某些(但不是全部)类比。我们表明,在规范场中将时空坐标作为隐变量处理,再现了在位形空间中导出的相同结果(即,我们不会丢失信息),而拟议的新处理方法提供了扩展这些信息的额外信息。其结果是额外的保守诺特电流。

英文摘要:

The paper discusses the mathematical consequences of the application of derived variables in gauge fields. Physics is aware of several phenomena, which depend first of all on velocities (like e.g., the force caused by charges moving in a magnetic field, or the Lorentz transformation). Applying the property of the second Noether theorem, that allowed generalised variables, this paper extends the article by Al-Kuwari and Taha (1991) with a new conclusion. They concluded that there are no extra conserved currents associated with local gauge invariance. We show, that in a more general case, there are further conserved Noether currents. In its method the paper reconstructs the clue introduced by Utiyama (1956, 1959) and followed by Al-Kuwari and Taha (1991) in the presence of a gauge field that depends on the co-ordinates of the velocity space. In this course we apply certain (but not full) analogies with Mills (1989). We show, that handling the space-time coordinates as implicit variables in the gauge field, reproduces the same results that have been derived in the configuration space (i.e., we do not lose information), while the proposed new treatment gives additional information extending those. The result is an extra conserved Noether current.
