Thanks I also found out that the 
* The ... algorithm applied to the Lane-Emden equation
:PROPERTIES:
:BEAMER_env: frame
:BEAMER_opt: allowframebreaks
:END:

* The original Lane-Emden equation

 #+begin_src latex :results latex replace :exports results :eval t
\begin{equation*}
  \begin{cases}
    y''(x)+\frac{2}{x}y'(x)+y^{n} &=0\\
    y(0) &= 1\\
    y'(0) &=0
  \end{cases}
\end{equation*}
where $n\in[0,5]$ is the polytropic index.
 #+end_src


Works fine, that is changing ** to *
