论文摘要
不久前，通过测量麦克斯韦代数以及所谓的ADS-Maxwell代数来扩展爱因斯坦重力的标准几何框架。在这封信中表明，通过使用randall-sundrum紧凑型程序，可以从五维的Chern-Simons重力动作中获得这些四维扩展爱因斯坦重力的作用。据发现，从魏玛 - 木材意义上讲，Inönü-wigner收缩程序既可以用来从ADS-Maxwell-Chern-Simons动作中获得Maxwell-Chern-Simons的作用，并从四维扩展Ads-Maxwell-Maxwell-Maxwell-Instein-Hilbert Action中获得4D的麦克斯韦重力。还表明，延长的四维重力属于标量调整理论的Horndeski家族。
Some time ago, the standard geometric framework of Einstein gravity was extended by gauging the Maxwell algebra as well as the so called AdS-Maxwell algebra. In this letter it is shown that the actions for these four-dimensional extended Einstein gravities can be obtained from the five-dimensional Chern-Simons gravities actions by using the Randall-Sundrum compactification procedure. It is found that the Inönü-Wigner contraction procedure, in the Weimar-Woods sense, can be used both to obtain the Maxwell-Chern-Simons action from the AdS-Maxwell-Chern-Simons action and to obtain the Maxwell extension of Einstein gravity in 4D from the four-dimensional extended AdS-Maxwell-Einstein-Hilbert action. It is also shown that the extended four-dimensional gravities belongs to the Horndeski family of scalar-tensor theories.
