2 + 1维宇宙学常数超引力规范对称性的推导

Derivation of Gauge Symmetries in Supergravity with a Cosmological Constant in 2 + 1 Dimensions

D. G. C. McKeon

摘要:

利用Dirac约束形式,在2 + 1维空间中分析了具有宇宙学常数的超引力的正则结构.第一类约束用于寻找满足超代数的两个玻色子和一个费米子规范对称性。假设宇宙学常数为负,这个新的代数就可以关闭,而不必调用运动方程或引入辅助场。

英文摘要:

The canonical structure of supergravity with a cosmological constant is analyzed in 2 + 1 dimensions using the Dirac constraint formalism. The first class constraints are used to find two Bosonic and one Fermionic gauge symmetries that satisfy a superalgebra. Provided the cosmological constant is negative, this novel algebra closes, without having to invoke the equations of motion or introducing auxiliary fields.
