引力Faddeev公式的一阶表示

First order representation of the Faddeev formulation of gravity

V. M. Khatsymovsky

摘要:

研究了引力的Faddeev公式,其中度规是由矢量场或十维场的四元组$f^A_λ$构成的,其中$λ= 1, 2, 3, 4$和$A = 1, ..., 10$是矢量指数w. R. t.欧几里得(或闵可夫斯基)十维时空。我们建议的Cartan-Weyl一个类型的表示。它是基于通过引入无穷小SO(10)联络来扩展变量集。通过运动方程排除这种联系,我们再现了原始的Faddeev作用。这种表示的一个独特之处是出现了局部SO(10)对称性破坏条件,使得SO(10)对称性仅为全局对称性,这与原来的Faddeev表述仅具有SO(10)对称性w完全一致。R. t.欧几里得十维时空的整体SO(10)旋转。我们还考虑类似的Barbero-Immirzi参数,可以自然地引入所考虑的表示。

英文摘要:

We study Faddeev formulation of gravity, in which the metric is composed of vector fields or the tetrad of the ten-dimensional fields, $f^A_λ$, where $λ= 1, 2, 3, 4$ and $A = 1, ..., 10$ is vector index w. r. t. the Euclidean (or Minkowsky) ten-dimensional spacetime. We propose representation of the type of the Cartan-Weyl one. It is based on extending the set of variables by introducing the infinitesimal SO(10) connection. Excluding this connection via equations of motion we reproduce the original Faddeev action. A peculiar feature of this representation is occurrence of the local SO(10) symmetry violating condition so that SO(10) symmetry is only global one in full correspondence with that the original Faddeev formulation just possesses SO(10) symmetry w. r. t. the global SO(10) rotation of the Euclidean ten-dimensional spacetime. We also consider analog of the Barbero-Immirzi parameter which can be naturally introduced in the considered representation.
