| Jun 19, 2017 at 7:18 | comment | added | Ryan Reich | @Qmechanic I have heard this claim before as well. Is, then, the expression I have written the "pseudotensor" (it is, manifestly, not globally defined but rather coordinate-dependent) referred to in this answer? | |

| Jun 19, 2017 at 7:01 | comment | added | Qmechanic♦ | Comments to the post (v1): 1. Technically, you are asking about the energy function, not the Hamiltonian, since no Legendre transformation $v\leftrightarrow p$ was actually performed. Consider to edit the post accordingly in various places to make this clear. 2. For the Hamiltonian formulation of GR, see the ADM formulation. | |
