"WebMay 23, 2015 · A finite field is, first of all, a set with a finite number of elements. An example of finite field is the set of integers modulo p, where p is a prime number. It is generally denoted as Z / p, G F ( p) or F p. We will use the latter notation. In fields we have two binary operations: addition (+) and multiplication (·).

WebDeﬁnition 3. A FIELD is a set F which is closed under two operations + and × such that (1) F is an abelian group under + and (2) F −{0} (the set F without the additive identity 0) is an abelian group under ×. Examples: Z/pZ is a ﬁeld, since Z/pZ is an additive group and (Z/pZ) − {0} = (Z/pZ)× is a group under multiplication.
