论文摘要
本说明描述了与角相关的局部泊松结构（直至同型）在Coframe（Palatinii-Cartan）形式上的四维重力相关。这是通过使用BFV形式主义来实现的。角结构尤其包含一个atiyah代数，该代数将内部对称性与差异形态形态融合在一起。还描述了与$ bf $理论的关系。
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.
