= Finite element degrees of freedom
{synonym}

A <finite element degree of freedom> is one of the <linear functionals> chosen to specify a local shape function in a finite-dimensional <vector space> $P$. Examples are <point evaluation functionals> and edge or cell <integrals>. The <finite element> is an <unisolvent finite element> when the complete list gives a <bijection> from $P$ to the corresponding list of real values.
