 | This page has been identified as a candidate for refactoring of basic complexity. Until this has been finished, please leave {{Refactor}} in the code.
New contributors: Refactoring is a task which is expected to be undertaken by experienced editors only. Because of the underlying complexity of the work needed, it is recommended that you do not embark on a refactoring task until you have become familiar with the structural nature of pages of $\mathsf{Pr} \infty \mathsf{fWiki}$.To discuss this page in more detail, feel free to use the talk page. When this work has been completed, you may remove this instance of {{Refactor}} from the code. |
 | This article needs to be linked to other articles. In particular: review existing links You can help $\mathsf{Pr} \infty \mathsf{fWiki}$ by adding these links. To discuss this page in more detail, feel free to use the talk page. When this work has been completed, you may remove this instance of {{MissingLinks}} from the code. |
Definition
Let $m, n \ge 1$ be natural numbers.
Let $U \subset \R^n$ be open.
Let $f : U \to \R^m$ be a mapping.
Then $f$ is a $C^k$-embedding if and only if $f$ is:
- injective
- a $C^k$-immersion
- a homeomorphism on its image
Rank
The rank of an embedding is the rank of its differential at any point.
