Comment(by salmanhb):
There seems to be an issue with returning the base ring of a
RationalFunctionField. Neither base() nor base_ring() return the correct
ring:
{{{
sage: K.<t> = FunctionField(QQ); K
Rational function field in t over Rational Field
sage: R1 = K.base(); R1
Rational function field in t over Rational Field
sage: R2 = K.base_ring(); R2
Rational function field in t over Rational Field
sage: R3.<s> = QQ[]; K3 = Frac(R3); K3
Fraction Field of Univariate Polynomial Ring in s over Rational Field
sage: R3
Univariate Polynomial Ring in s over Rational Field
sage: K3.base() == R3
True
}}}
