+            \footnote{$\left( \boldsymbol{z}_j \right)_i $ is a slight abuse of notation.
+            What is actually meant is the component of $\boldsymbol{z}_j$ that is associated
+            with the VN $i$, i.e., $\left( \boldsymbol{T}_j^\text{T} \boldsymbol{z}_j \right)_i$.\\

+            $\Pi_{\mathcal{P}_{d_j}}, \hspace{1mm} j\in\mathcal{J}$. Many
