Field of rational functions

[edit]

In mathematics, given a field K, the field of rational functions K(X) is the field of all rational functions in the variable X with coefficients in K. It is the field of fractions of the polynomial ring K[X].

The field of rational functions is not to be confused with the field of rationals, which is the field of fractions for the ring of integers.

Given a field K, the ring K[X] of polynomials in the variable X with coefficients in K is an integral domain so that the field of fractions of K[X] can be constructed. K(X)/K is a field extension of infinite degree.
