A ring is a set R R together with two operations (+) (+) and (\cdot) (⋅) satisfying the following properties (ring axioms): (1) R R is an abelian group under addition. That is, R R is closed under addition, there is an additive identity (called 0 0 ), every element a\in R a ∈ R has an additive inverse -a\in R ...

That is, a field is a set F F with two operations, + + and \cdot ⋅, such that (1) F F is an abelian group under addition; (2) F^* = F - \ { 0 \} F ∗ = F − {0} is an abelian group under multiplication, where 0 0 is the additive identity in F F;
WebThe field L is the algebraic closure of K ( S) and algebraic closures are unique up to isomorphism; this means that the automorphism can be further extended from K ( S) to L . As another application, we show that there are (many) proper subfields of the complex number field C which are (as fields) isomorphic to C.
