开放引力系统的正则括号

A canonical bracket for open gravitational system

Laurent Freidel

摘要:

本文证明了最近提出的表示广义角代数的Barnich-Troessaert括号的推广可以作为广义引力拉格朗日量的正则括号。这种扩展有效地允许人们通过嵌入场将辛通量重新吸收到拉格朗日量的敷料中。它还意味着,规范泊松括号的收费形式的一个表示的扩展角对称代数。

英文摘要:

This paper shows that the generalization of the Barnich-Troessaert bracket recently proposed to represent the extended corner algebra can be obtained as the canonical bracket for an extended gravitational Lagrangian. This extension effectively allows one to reabsorb the symplectic flux into the dressing of the Lagrangian by an embedding field. It also implies that the canonical Poisson bracket of charges forms a representation of the extended corner symmetry algebra.
