Frobenius endomorphism: Measurement, Definition & Fixed points of the Frobenius endomorphism

In commutative algebra and field theory, the Frobenius endomorphism (after Ferdinand Georg Frobenius) is a special endomorphism of commutative rings with prime characteristic p, an important class that includes finite fields. The endomorphism maps every element to its pth power. In certain contexts it is an automorphism, but this is not true in general.
