Palatini Formalism of 5-Dimensional Kaluza-Klein Theory

You Ding, Yongge Ma, Muxin Han +1

The Einstein field equations can be derived in $n$ dimensions ( $n > 2$ ) by the variations of the Palatini action. The Killing reduction of 5-dimensional Palatini action is studied on…

Killing Reduction of 5-Dimensional Spacetimes

Xuejun Yang, Yongge Ma, Jianbing Shao +1

In a 5-dimensional spacetime ( $M, g_{ab}$ ) with a Killing vector field $ξ^{a}$ which is either everywhere timelike or everywhere spacelike, the collection of all trajectories of $ξ^{a}$ …
