\section{Timely Throughput Model}

\subsection{The Model}
\begin{frame}[t]{Guarantee per packet Hard Deadline Constraints}
  \begin{block}
    \begin{itemize}
    \item Clients generate packets with fixed period $\tau$.  .
    \item Deadline = Period.
    \item Packets expire and are dropped if not delivered by the deadline.
    \item Hence delay of successfully delivered packet is at most $\tau$.
    \item Delivery ratio of packets that meet deadline for client $n$ should be at least $q_{n}$, i.e. 
$$\liminf\limits_{T\to\infty} \frac{1}{T}\sum\limits_{t=1}^{T}\mathbbm{1}\{\mbox{client $i$'s packet is delivered in frame $t$}\}\geq q_{i}.$$
   \end{itemize}
  \end{block}
\end{frame}

\begin{frame}[t]{A Minimum Delivery-Ratio Required.}
  \begin{block}
    \begin{itemize}
    \item Delivery ratio of packets that meet deadline for client $n$ should be at least $q_{n}$, i.e. 
$$\liminf\limits_{T\to\infty} \frac{1}{T}\sum\limits_{t=1}^{T}\mathbbm{1}\{\mbox{client $i$'s packet is delivered in frame $t$}\}\geq q_{i}.$$
   \end{itemize}
  \end{block}

I think your block environments need titles; thus

\begin{block}{A nice block}

rather than just

\begin{block}

A more minimal example that reproduces the problem is

\documentclass{beamer}
\begin{document}
 \begin{frame}{A nice frame}
   \begin{block}{A nice block}  %Comment out {A nice block} to crash TeX.
   \begin{itemize}
   \item abc
   \end{itemize}
   \end{block}
 \end{frame}
\end{document}

Finally, note that \[ and \] are preferable to $$.

  • 1
    Or just \begin{block}{}...\end{block} if no title is desired for the block. – Gonzalo Medina Aug 1 '13 at 21:57
