+The theorem is proved in a slightly different context in \cite{krause2005near}; we
 repeat the proof here for the sake of completeness. Using the chain rule for
 the conditional entropy we get:
-\begin{displaymath}\label{eq:chain-rule}
+\begin{equation}\label{eq:chain-rule}
     V(S) = H(y_S) - H(y_S \mid \beta) 
     = H(y_S) - \sum_{i\in S} H(y_i \mid \beta)
-\end{displaymath}
+\end{equation}
 where the second equality comes from the independence of the $y_i$'s
 conditioned on $\beta$. Recall that the joint entropy of a set of random
 variables is a submodular function. Thus, our value function is written in
