RationalFunctionField class

A class for fields of rational functions. It is a subclass of nzmath.ring.QuotientField.

methods

createElement(*seedarg, **seedkwd)

getQuotientField()

issubring(other)

issuperring(other)

unnest()

if self is a nested RationalFunctionField i.e. its coefficientField is also a RationalFunctionField, then the function returns one level unnested RationalFunctionField.

For example:
RationalFunctionField(RationalFunctionField(Q, "x"), "y").unnest()
returns
RationalFunctionField(Q, sets.Set(["x","y"])).

gcd(a, b)

Inherited from nzmath.ring.Field.
