论文摘要
我们证明,对于Friedmann-Lemaitre-Robertson-Walker指标,任意维度中任何通用引力理论的场方程都是完美的流体类型。将常规Lovelock和$ \ Mathcal {f}(r,\ Mathcal {g})$理论的情况作为示例。
We prove that for the Friedmann-Lemaitre-Robertson-Walker metric, the field equations of any generic gravity theory in arbitrary dimensions are of the perfect fluid type. The cases of general Lovelock and $\mathcal{F}(R, \mathcal{G})$ theories are given as examples.
