The order of a finite field is always a prime or a power of a prime (birkhoff and mac lane 1996). In other words, α ∈ gf (q) is called a primitive element if it is a primitive (q − 1) th root of unity in gf (q); A finite extension is an extension that has a finite degree. As with any field, a finite field is a set on which the operations of multiplication, addition, subtraction and division are defined and satisfy certain basic rules. Given a field extension l / k and a subset s of l, there is a smallest subfield of l that contains k and s. Finite fields are important in number theory, algebraic geometry, galois theory, cryptography, and coding theory. Finite fields were named galois fields to honor évariste galois. In mathematics, a finite field or galois field is a field that contains a finite number of elements. Such a finite projective space is denoted by pg( n , q ) , where pg stands for projective geometry, n is the geometric dimension of the geometry and q is the size (order) of the finite field used to construct the geometry.

Infinite verbform) bezeichnet man wortformen eines verbs, die bestimmte grammatische merkmale ausdrücken und dies mit besonderen syntaktischen eigenschaften verbinden; A field with a finite number of elements is called a galois field. Given a field extension l / k and a subset s of l, there is a smallest subfield of l that contains k and s. A finite field is a field with a finite field order (i.e., number of elements), also called a galois field. Newer post older post home. There are infinitely many different finite fields. The most common examples of finite fields are given by the integers mod p when. The most common examples of finite fields are given by the integers mod p when.
