AlgebraicKernel_d_1::MakeCoprime_1 Concept Reference
Univariate Algebraic Kernel

Definition

Computes for a given pair of univariate polynomials \( p_1\), \( p_2\) their common part \( g\) up to a constant factor and coprime parts \( q_1\), \( q_2\) respectively.

That is, it computes \( g, q_1, q_2\) such that:

\( c_1 \cdot p_1 = g \cdot q_1\) for some constant \( c_1\) and

\( c_2 \cdot p_2 = g \cdot q_2\) for some constant \( c_2\), such that \( q_1\) and \( q_2\) are coprime.

It returns true if \( p_1\) and \( p_2\) are already coprime.
