Abstract

We give a detailed canonical analysis of the n-dimensional f(Riemann) gravity, correcting the earlier results in the literature. We also write the field equations in the Fischer–Marsden form which is amenable to identifying the non-stationary energy on a spacelike hypersurface. We give pure R² and

RμνRμν

theories as examples.

通用 f(黎曼)引力中的约束和时间演化

我们对 n 维 f(黎曼)引力进行了详细的规范分析，修正了文献中的早期结果。我们还以费舍尔-马斯登形式写出了场方程，这有利于识别空间似超曲面上的非稳态能量。我们给出了纯 R2 和 RμνRμν 理论作为例子。
