规范AdS-Maxwell代数与引力

Gauged AdS-Maxwell algebra and gravity

R. Durka, J. Kowalski-Glikman, M. Szczachor

摘要:

我们通过添加额外的生成元$\mathcal{Z}_{ab}$来变形反德西特代数,以这种方式形成麦克斯韦代数的负宇宙学常数对应物。我们利用约束BF理论对这个代数进行了规范,并构造了一个动力学模型。结果表明,由此产生的理论是由爱因斯坦-嘉当作用量与霍尔斯特项描述,和规范场与麦克斯韦发电机$\mathcal{Z}_{ab}$只出现在拓扑条款,不影响动力学场方程。我们简要地评论这个结构的扩展,这将导致一个非平凡的麦克斯韦场动力学。

英文摘要:

We deform the anti-de Sitter algebra by adding additional generators $\mathcal{Z}_{ab}$, forming in this way the negative cosmological constant counterpart of the Maxwell algebra. We gauge this algebra and construct a dynamical model with the help of a constrained the BF theory. It turns out that the resulting theory is described by the Einstein-Cartan action with Holst term, and the gauge fields associated with the Maxwell generators $\mathcal{Z}_{ab}$ appear only in topological terms that do not influence dynamical field equations. We briefly comment on the extension of this construction, which would lead to a nontrivial Maxwell fields dynamics.
