 It is also possible to add non dynamical degrees of freedom (\dof) to the open string endpoints.
-They are known as \emph{Chan-Paton factors}~\cite{Paton:1969:GeneralizedVenezianoModel}.
+They are known as \emph{Chan-Paton factors}~\cite{Chan:1969:GeneralizedVenezianoModel}.
 They have no dynamics and do not spoil Poincaré or conformal invariance in the action of the string.
 Each state can then be labelled by $i$ and $j$ running from $1$ to $N$.
 Matrices $\tensor{\lambda}{^a_{ij}}$ thus form a basis for expanding wave functions and states:
