论文摘要
我们认为模仿Horava重力，其中使用模拟引力的标量场用于构造差异不变模型，从而将同步仪减少到Horava重力。可以证明，加剧动作增加了吉本斯·乌尔克（Gibbons-hawking-York）术语和模仿horava动作对于拓扑为$ r \ timesσ$的流形，其中$σ$是三维超曲面；否则，模仿Horava动作不包含任何表面术语。
We consider mimetic Horava gravity, where the scalar field of mimetic gravity was used in the construction of diffeomorphism invariant models reducing to Horava gravity in the synchronous gauge. It will be shown that the gravitational action with the addition of the Gibbons-Hawking-York term and the mimetic Horava action are equivalent for manifolds whose topology is $R \times Σ$, where $Σ$ is a three-dimensional hypersurface; otherwise, the mimetic Horava action does not contain any surface terms.
