Pete, the latex isn't working in the private messages, so I posted this:(adsbygoogle = window.adsbygoogle || []).push({});

Do you agree with the following mass of statements (sorry for the length), I'll number them for reference

#1)

In the weak field, g_uv = n_uv + h_uv, h_uv <<1, and we raise and lower indices with n_uv, not h_uv.

#2)

In the weak field the Christoffel symbols are

[edit] factor of 1/2 added [/end edit]

[tex]

\Gamma^c{}_{ab} = \frac{1}{2} n^{cd} (\partial_a\, g_{bd} + \partial_b\, g_{ad} - \partial_d \, g_{ab})

[/tex]

#3)

In the weak field, the Riemann is

[tex]R^a{}_{bcd} = \partial_c \, \Gamma^a{}_{bd} - \partial_d \,\Gamma^a{}_{bc} [/tex]

ps - glad you're out of surgery & hope you're doing as well as you sound.
