Theorem
Let $\struct {\tilde M, \tilde g}$ be an oriented Riemannian manifold.
Let $\struct {M, g}$ be an orientable hypersurface with an induced metric.
Let $N$ be a unit global normal vector for $M$.
Let $\rd V_g$ be the Riemannian volume form.
Then Riemannian volume form is given by:
- $\rd V_g = \valueat {\paren {N \lrcorner \rd V_{\tilde g} } } M$
where $\lrcorner$ denotes the interior multiplicaiton.
