### Definition with symbols

A function on a group is termed a **uniform power map** or **universal power map** if there exists an integer such that for all in .

## Relation with other properties

### Automorphisms and endomorphisms

- Uniform power endomorphism is a universal power map that is also an endomorphism
- Uniform power automorphism is a universal power map that is also an automorphism

For Abelian groups, all uniform power maps are endomorphisms.
