Old description:
New description:
Singular has polynomial rings over function fields. However, Sage makes no
use of it:
{{{
sage: P.<a> = QQ[]
sage: F = P.fraction_field()
sage: type(F['x','y'])
<class
'sage.rings.polynomial.multi_polynomial_ring.MPolynomialRing_polydict_domain_with_category'>
sage: F = FunctionField(QQ,'a')
sage: type(F['x','y'])
<class
'sage.rings.polynomial.multi_polynomial_ring.MPolynomialRing_polydict_domain_with_category'>
}}}
