 %\subsection{Problem and notations}
 %Let us begin by introducing the following notation.
 %We will use the following notation to formally discuss the model.  
-Given a graph $G=(V,E)$, for a node $v\in V$ we denote by $\neigh{u}$
+Given a graph $G=(V,E)$, for a node $v\in V$ we denote by $\neigh{v}$
 the neighborhood of $v$. By extension, for any subset of nodes $S\subseteq V$,
 $\neigh{S}\defeq \bigcup_{v\in S}\neigh{v}$ will denote the neighborhood of
 $S$. The notion of influence in the graph is captured by a function
