\begin{ccRefConcept}{PolynomialTraits_d::UnivariateContentUpToConstantFactor}

\ccDefinition

This \ccc{AdaptableUnaryFunction} computes the content of a 
\ccc{PolynomialTraits_d::Polynomial_d} 
with respect to the univariate (recursive) view on the 
polynomial {\em up to  a constant factor (utcf)}, that is, 
it computes the $gcd\_utcf$ of all coefficients  with respect to one variable. 

Remark: This is called \ccc{UnivariateContentUpToConstantFactor} for 
symmetric reasons with respect to \ccc{PolynomialTraits_d::UnivariateContent} 
and \ccc{PolynomialTraits_d::MultivariateContent}. 
However, a concept \ccc{PolynomialTraits_d::MultivariateContentUpToConstantFactor} 
does not exist since the result is trivial.
