Compactness

That's my contribution for the day done. The Anome

Re: removal of the condition that the region S be compact - I doubt that one can do this unconditionally.

You are correct. Either the manifold must be compact, or the integrand must have compact support. sorry for the sloppiness. i think i will just change it back.

Re: Infinite plane of mass

The behavior is an approximative case only. It is the closest to "ideal" when you are very close to the black hole's event horizon. At least that is what I remember from a website which I'll need to look up. :-)

Generalization

5.95.187.184 (talk)I would like to recall your attention about this section, in particular about the first subsection: Multiple dimensions. In fact, I think that this one would actually benefit in being inserted as a sub-subsection of the generalization to the Riemaniann Manifold, for which the equation is: ${\int _{M}{\text{div}}(X)\ \nu _{g}=\int _{\partial M}<X,N>\nu _{\hat {g}}}$, where $\nu$ is for the riemaniann volume form of the riemannian Manifolds, namely, $(M,g)$ and $(\partial M,{\hat {g}})$ (the last one considered as a submanifold of $M$ with the inclusion as embedding), $X$ is a vector field, and $N$ is the versor normal field defined on $\partial M$. Considered this equation, the subsection Multiple dimensions is just a corollary, with $M$ considered as a submanifold of $\mathbb {R} ^{n}$

Wikiversity sister link added

I added a pedagogical introduction at v:Divergence theorem. As per regs, the link is situated at the bottom under "External links". The editors of this article can choose to mention and/or link to v:Divergence theorem in the lede or elsewhere else. If there is anything in the Wikipedia article you would like to have sent to Wikiversity, leave a note at v:User talk:Guy vandegrift and I will help you. At Wikiversity we use lots of subpages, giving us more freedom to add material that might not interest all readers.--Guy vandegrift (talk) 03:43, 19 March 2021 (UTC)
