\section{Main Result 1}\label{smain1} 



\begin{prop}\label{prop1}{\rm \cite[Fact 2.5]{HLA} (Dimension Theorem)}  If $A\in\Rnn$, then $\rank A + \ker A = n$.
\end{prop}

 
 \begin{ex}\label{ex1}  {\rm Figure \ref{fig1} is an example of a figure.}
   \begin{figure}[!h]
\begin{center}\scalebox{.5}{\includegraphics{K333}} 
\caption{The  loop graph $G_{\ref{fig1}}$ for Example \ref{ex1}.} \label{fig1}
\end{center}
\end{figure}
\end{ex}


\begin{thm}\label{thm3} If $G$ is a graph, then $\kappa_e(G)\le \kappa_v(G)$.
\end{thm}
\bpf  This is not a proof but should be.  This theorem does not follow from Proposition \ref{prop1}.
