Definition

This AdaptableUnaryFunction computes the square-free part of a polynomial of type PolynomialTraits_d::Polynomial_d up to a constant factor.

A polynomial $p$ can be factored into square-free and pairwise coprime non-constant factors $g_i$ with multiplicities $m_i$ and a constant factor $a$ , such that $p = a \cdot g_1^{m_1} \cdot ... \cdot g_n^{m_n}$ , where all $g_i$ are canonicalized.

Given this decomposition, the square free part is defined as the product $g_1 \cdot ... \cdot g_n$ , which is computed by this functor.
