 and the global numbering of vertices in the vertex set is facilitated
 via the {\em local to global map} defined by:
 \begin{equation}
-\forall T\in\mathcal{T}_h, 0\leq i \leq d: g_T(l) = j \Leftrightarrow x_{T,l} = x_{j} .
+\forall T\in\mathcal{T}_h, 0\leq l \leq d: g_T(l) = j \Leftrightarrow x_{T,l} = x_{j} .
 \end{equation}
 The map $g_T : \{0,\ldots,d\}\to\mathbb{N}$ 
 plays also a very important role in the implementation of the finite element method.
