Poisson结构非对易空间上的SL(2,C)引力

SL(2,C) gravity on noncommutative space with Poisson structure

Yan-Gang Miao, Shao-Jun Zhang

摘要:

爱因斯坦的引力理论可以用旋量符号表示为SL(2,C)规范理论。本文考虑具有Poisson结构的非对易空间,并在此空间上构造了一个SL(2,C)引力公式。使用协变坐标技术,我们建立了一个规范不变的行动,其中,根据Seiberg-Witten映射,物理自由度表示在他们的交换对应的非交换参数的一阶。

英文摘要:

The Einstein's gravity theory can be formulated as an SL(2,C) gauge theory in terms of spinor notations. In this paper, we consider a noncommutative space with the Poisson structure and construct an SL(2,C) formulation of gravity on such a space. Using the covariant coordinate technique, we build a gauge invariant action in which, according to the Seiberg-Witten map, the physical degrees of freedom are expressed in terms of their commutative counterparts up to the first order in noncommutative parameters.
