Definition

Let $M$ be an $n$-dimensional $C^1$ manifold.

Let $\ds \Lambda^k T^* M = \bigcup_{p \mathop \in M} \set p \times \map {\Lambda^k} {T_p^*M}$, endowed with its natural structure as a $C^0$ manifold.



A differential $k$-form is a continuous mapping:

$\omega : M \to \Lambda^kT^* M$

satisfying:

$\forall p \in M \map {\paren {\pi \circ \omega} } p = p$

where $\pi : \Lambda^k T^*M \to M$ is the projection onto the first argument, defined by:

$\map \pi {p, v} = p$


In other words, a differential form is a continuous mapping $\omega$ that assigns each point $p \in M$ an alternating $k$-form $\map \omega p$ on $T_p M$.
