\begin{thm}
\label{thm:stability}
When $\rho < 1$, for all $n$, $Q^n(t) \Rightarrow Q^n(\infty)$ as
$t \to \infty$.
\end{thm}
\newpage
\begin{thm}
\label{thm:convergence}
For any $q(0)$, when $Q^n(0)/n \to q(0)$ almost surely as $n \to \infty$, then $Q^n(t)/n \to q(t)$ almost surely and uniformly on
compact sets $[0,T]$.
\end{thm}
\newpage
\begin{thm}
\label{thm:fixedPoint}
As $t \to \infty$, $q(t) \to q(\infty)$ for all $q(0)$.
\end{thm}
\newpage
\begin{thm}
\label{thm:interchange}
As $n \to \infty$, $Q^n(\infty)/n \to q(\infty)$ in probability.
