Definition
Let $\struct {M, g}$ be an oriented $n$-dimensional Riemannian manifold.
Let $T^* M$ be the cotangent bundle of $M$.
Let $\tuple {\epsilon^1, \ldots, \epsilon^n}$ be a local oriented orthonormal coframe of $T^* M$.
The Riemannian volume form, denoted by $\rd V_g$, is an $n$-form such that:
- $\rd V_g = \epsilon^1 \wedge \ldots \wedge \epsilon^n$
