## Curl and Existence of Potential Functions |

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z | overview |

Let be a continuous differentiable vector field defined on an open set Assume that is conservative, i.e. has a potential function. Then

If is simply connected, then the converse holds.

Examples of simply connected open sets are open balls, open cubes or the entire space Open subsets with a hole are not simply connected.

In the case when is - dimensional the same statements hold, if one replaces the curl by the scalar curl.

In - space examples of simply connected sets are open rectangles, open circles or the entire plane.
