% If you have a file called "university-logo-filename.xxx", where xxx
% is a graphic format that can be processed by latex or pdflatex,
% resp., then you can add a logo as follows:

\pgfdeclareimage[height=0.5cm]{university-logo}{lmdlogo}
\logo{\pgfuseimage{university-logo}}



% Delete this, if you do not want the table of contents to pop up at

% Structuring a talk is a difficult task and the following structure
% may not be suitable. Here are some rules that apply for this
% solution: 

% - Exactly two or three sections (other than the summary).
% - At *most* three subsections per section.
% - Talk about 30s to 2min per frame. So there should be between about
%   15 and 30 frames, all told.

% - A conference audience is likely to know very little of what you
%   are going to talk about. So *simplify*!
% - In a 20min talk, getting the main ideas across is hard
%   enough. Leave out details, even if it means being less precise than
%   you think necessary.
% - If you omit details that are vital to the proof/implementation,
%   just say so once. Everybody will be happy with that.

\section{Motivation}

\subsection{The Basic Problem That We Studied}

\begin{frame}
  \frametitle{Make Titles Informative. Use Uppercase Letters.}
  \framesubtitle{Subtitles are optional.}
  % - A title should summarize the slide in an understandable fashion
  %   for anyone how does not follow everything on the slide itself.

  \begin{itemize}
  \item
    Use \texttt{itemize} a lot.
  \item
    Use very short sentences or short phrases.
  \end{itemize}
\end{frame}

\begin{frame}
  \frametitle{Make Titles Informative.}

  You can create overlays\dots
  \begin{itemize}
  \item using the \texttt{pause} command:
    \begin{itemize}
    \item
%
\begin{equation}
\left \lbrace
\begin{array}{ll}
\partial_t \vect{\sigma_0}(t) = M^{\flat} \vect{\sigma_0}(t,0)  + \ket{b} \Upsilon(t)  \\
g(t)  =  \bra{c} \vect{\sigma_0}(t,0) \, ,
\end{array}
\right .
\label{psig}\end{equation}
%

      \pause
    \item    
%
\begin{multline}
\Dth(t)=\bra{c(t)}\Phi(t,0)\Deta^r_0\\
+\bra{c}(t)\int_0^t\Phi(t,\tau)\ket{b}(\tau)\Dth_0(\tau)d\tau
\label{propag}\end{multline}
%

    \end{itemize}
  \item
    using overlay specifications:
    \begin{itemize}
    \item<3->
      First item.
    \item<4->
      Second item.
    \end{itemize}
  \item
with the definition of the propagator as:
%
\begin{equation}
\partial_t\Phi(t,\tau)=M(t)\Phi(t,\tau)\,;\quad\Phi(\tau,\tau)=I\;,
\end{equation}
%
with the identity matrix $I$.

    using the general \texttt{uncover} command:
    \begin{itemize}
      \uncover<5->{\item
        First item.}
      \uncover<6->{\item
        Second item.}
    \end{itemize}
  \end{itemize}
