我们从高斯-邦纳作用量出发推导出引力哈密顿量,并跟踪所有的表面项。这是使用正交框架和形式的语言来尽可能保持整洁。哈密顿量中的表面项给出了一个非常简单的时空总能量的表达式。该表达式与预印本hep-th/0212292中的能量表达式一致。然而,我们可以应用我们的结果,无论背景的选择和时空的对称性如何。
We derive the gravitational Hamiltonian starting from the Gauss–Bonnet action, keeping track of all surface terms. This is done using the language of orthonormal frames and forms to keep things as tidy as possible. The surface terms in the Hamiltonian give a remarkably simple expression for the total energy of a spacetime. This expression is consistent with energy expressions found in Preprint hep-th/0212292. However, we can apply our results whatever the choice of background and whatever the symmetries of the spacetime.
