超重力超群BF action

Supergroup BF action for supergravity

C. Ramirez, E. Rosales

摘要:

广义相对论可以表述为一个有约束的SU(2)BF理论,正如普列巴斯基所证明的那样。宇宙学常数项可以从约束项中得到,遵循运动方程的一致性,正如克拉斯诺夫最近所证明的那样。我们考虑一个$OSp(2|1)$不变的,超引力扩展的这个理论,其中的运动方程和约束的一致性,以及有助于宇宙学常数项汤森的超引力。Kalb-Ramond不变性是简短的讨论。

英文摘要:

General relativity can be formulated as a SU(2) BF-theory with constraints, as has been shown, by Plebański. The cosmological constant term can be obtained from the constraint term, following from the consistency of the equations of motion, as recently shown by Krasnov. We consider an $OSp(2|1)$ invariant, supergravity extension of this theory, for which the consistency of the equations of motion and the constraints contribute as well to the cosmological constant terms of Townsend's supergravity. The Kalb-Ramond invariance is shortly discussed.
