Covariant divergence question from Landau and Lifshitz

[maverick280857]

Hi everyone,

I'm trying to work through section 86 of Landau and Lifgarbagez volume 2 (The Classical Theory of Fields).

Basically, I am unable to get equation (86.6) from equations (86.4) and (86.5). I've detailed my working/question in the attached jpg file. I would appreciate any inputs.

Thanks in advance!
Cheers
Vivek

I bet they've calculated \partial \sqrt{-g} / \partial x^{\mu} somewhere.

Take a look at section 1.7 in Eric Poisson's excellent notes,

Better yet, see if your library has a copy of the excellent book, A Relativist's Toolkit: The Mathematics of Black Hole Mechanics, into which the notes evolved.

George, thanks a lot for this very useful link! Unfortunately, my school library does not have this book.

Maybe you are lucky with the pages available there.
You could also have a look for a preview on Amazon.
