Function - Invariant

1 - About

A function (or property) is invariant under a certain family of transformations if its value does not change when a transformation from this family is applied to its argument.

See also: Function - Covariant

3 - Example

The area of a 2D surface is invariant under 2D rotations, since rotating a 2D surface does not make it any smaller or bigger.
