Definition
A map [ilmath]f:M\rightarrow N[/ilmath] between two smooth manifolds [ilmath](M,\mathcal{A})[/ilmath] and [ilmath](N,\mathcal{B})[/ilmath] (of not necessarily the same dimension) is said to be smooth[1] if:
- [math]\forall p\in M\exists\ (U,\varphi)\in\mathcal{A},\ p\in U\text{ and }(V,\psi)\in\mathcal{B}[/math] such that [math]F(U)\subseteq V\wedge \psi\circ F\circ\varphi^{-1}[/math] is smooth
