共架形式体系下四维广义相对论的角隅结构

Corner Structure of Four-Dimensional General Relativity in the Coframe Formalism

Giovanni Canepa, Alberto S. Cattaneo

AI总结:

该研究利用BFV形式体系,得到共架形式下四维引力角隅的局域泊松结构,发现其含耦合内部对称性与微分同胚的Atiyah李代数胚,并阐明了与BF理论的关系。

摘要:

本短文描述了共架(Palatini–Cartan)形式体系下,与四维引力的角隅相关的局域泊松结构(直至同伦)。这一结果通过BFV形式体系实现。该角隅结构特别包含一个将内部对称性与微分同胚耦合的Atiyah李代数胚。文中还阐述了其与$BF$理论的关联。

英文摘要:

This note describes a local Poisson structure (up to homotopy) associated to corners in four-dimensional gravity in the coframe (Palatini--Cartan) formalism. This is achieved through the use of the BFV formalism. The corner structure contains in particular an Atiyah algebroid that couples the internal symmetries to diffeomorphisms. The relation with $BF$ theory is also described.
