## 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.
