我们将最大对称时空上的引力场表述为规范理论,并通过牛顿引力常数的级数展开研究线性化引力场的高阶形式对称性。为将引力视为规范理论,我们采用了基于Cartan几何的MacDowell-Mansouri表述。我们证明了在Minkowski时空的线性化引力中存在1-形式对称性。此外,对于具有小宇宙学常数的其他最大对称时空(de Sitter和anti-de Sitter时空),我们证明了相应线性化引力中存在近似的1-形式对称性,并详细说明了其对宇宙学常数的显式依赖。
英文摘要
We formulate the gravitational field on maximally symmetric spacetimes as a gauge theory, and investigate higher-form symmetries of the linearized gravitational field via a series expansion in Newton's gravitational constant. To treat gravity as a gauge theory, the MacDowell-Mansouri formulation based on Cartan geometry is utilized. We show the existence of a 1-form symmetry in linearized gravity on Minkowski spacetime. Furthermore, for other maximally symmetric spacetimes (de Sitter and anti-de Sitter spacetimes) with a small cosmological constant, we demonstrate the existence of an approximate 1-form symmetry in the corresponding linearized gravity, detailing its explicit dependence on the cosmological constant.
