If U is an open subset of \({\mathbb{R}}^{n}\), we say that a map \(\phi: U\longrightarrow {\mathbb{R}}^{m}\) is smooth if it has continuous partial derivatives of all orders. More generally, if \(X \subset {\mathbb{R}}^{n}\) is not necessarily open, we say that a map \(\phi: X\longrightarrow {\mathbb{R}}^{n}\) is smooth if for each xX there exists an open set U of \({\mathbb{R}}^{n}\) containing \(x\) such that ϕ can be extended to a smooth map on U. A diffeomorphism of \(X \subseteq {\mathbb{R}}^{n}\) with \(Y \subseteq {\mathbb{R}}^{m}\) is a homeomorphism \(F: X\longrightarrow Y\) such that both F and F −1 are smooth. We will assume as known the following useful criterion.
