论文摘要
提供了一种简单的方法，用于计算汉密尔顿在时空曲率中线性的理论密度。结果表明，流失函数和移位矢量仍会产生主要约束，而诱导的度量导致了非平凡的演化方程。尽管从形式上意义上讲，但始终可以获得相应的汉密尔顿密度。
A straightforward method to compute Hamilton's density for theories that are linear in the spacetime curvature is provided. It is shown that the lapse function and shift vector still give rise to primary constraints, while the induced metric gives rise to nontrivial evolution equations. The corresponding Hamilton's density can always be obtained, albeit in a formal sense.
