Definition
Let $M$ be an $n$-dimensional manifold.
Let $p \in X$, and let $U \subseteq M$ be a neighbourhood of $p$.
Let $\phi$ be the local coordinate map of $M$ such that:
- $\map \phi p = \tuple {\map {x_1} p, \map {x_2} p, \ldots \map {x_n} p}$
The component mappings $\tuple {x_1, x_2, \ldots x_n}$ of $\phi$ are known as the local coordinates around $p$.
