- class sage.rings.polynomial.polynomial_singular_interface.PolynomialRing_singular_repr¶
Implements methods to convert polynomial rings to Singular.
This class is a base class for all univariate and multivariate polynomial rings which support conversion from and to Singular rings.
- class sage.rings.polynomial.polynomial_singular_interface.Polynomial_singular_repr¶
Implements coercion of polynomials to Singular polynomials.
This class is a base class for all (univariate and multivariate) polynomial classes which support conversion from and to Singular polynomials.
Due to the incompatibility of Python extension classes and multiple inheritance, this just defers to module-level functions.
Trueif this ring’s base field or ring can be represented in Singular, and the polynomial ring has at least one generator.
The following base rings are supported: finite fields, rationals, number fields, and real and complex fields.
