ECT自旋-引力场理论在黎曼背景时空下的表述和规范条件

ECT自旋-引力场理论(或称TFL自旋-引力场理论)是Einstein引力场理论在有挠弯曲时空中的推广理论,它消除了Einstein引力场理论与Dirac电子场理论之间的矛盾,其简化形式的ECT自旋-引力场理论有Einstein引力场理论极限,因此,它应是比Einstein引力场理论更加正确的引力理论.标准的ECT自旋-引力场理论认为自旋-引力场完全是一种有挠弯曲时空的几何结构,为了得到清晰的物理图像和对具体的引力问题进行分析,我们需要认为自旋-引力场也是一种在黎曼背景时空下的动力学场.本文将ECT自旋-引力场理论中的自旋-引力场看作是黎曼背景时空的几何结构及在黎曼背景时空下的动力学场的复合体,自旋-引力场在给定黎曼时空背景下的物理效应用动力学场描述.应用这种思想,我们建立了ECT自旋-引力场理论在黎曼背景时空下的表述,并且在黎曼背景下讨论了自旋场和引力场的规范条件.

Presentation and Gauge Condition of ECT Spin-Gravity Fields Theory Under Riemann Background Space-Time

ECT spin-gravity theory is the promotion of the Einstein gravitational field theory in curved space-time with torsion, it eliminates the contradiction between the Einstein gravitational field theory and the Dirac electron field theory. The simple form of ECT spin-gravity theory has a limit of Einstein gravitational field theory, so the ECT spin-gravity theory should be more correct than the Einstein gravitational field theory. In order to obtaining a clear physical picture and analyzing a specific physical problem, the Riemann background presentation of ECT spin-gravity has been established through separating the physical effect of spin-gravity field from the given P, iemann background space-time in this article. In this article, the gauge conditions has been discussed in the FZiemann background presentation of ECT spingravit3,.
