I have something like the following in a tex document:

some text ...

\[ T_y = \left\{ \begin{array}{ll}
          x + \alpha & \mbox{if $\alpha = \beta$}\\
          x^2 + \beta & \mbox{else} \end{array} \right. \]

some text again ...

Question: is it possible that the formula is adjusted at left and the second test comes in front of the formula (at right), and not immediately under it ?

Welcome to TeX.SX! Would you try making your question clearer? It's not clear what text you're referring to. –  egreg Jun 30 '12 at 17:45
    
What do you mean with 'above it'? –  Sigur Jun 30 '12 at 20:44

I think you might like the wrapfig package for this.

enter image description here

\documentclass{article}
\usepackage{amsmath}    % for cases environment (and lots more)
\usepackage{wrapfig}    % for wrapfigure environment
\usepackage{lipsum}     % for sample text

\begin{document}

\lipsum[1]
\begin{wrapfigure}{l}{.5\textwidth}
\begin{equation}
 T_y = 
    \begin{cases}
          x + \alpha & \text{if $\alpha = \beta$}\\
          x^2 + \beta & \text{else}
    \end{cases}
\end{equation}
\end{wrapfigure}

\lipsum[2]
\end{document}

Great, is it also possible to reduce the white space on top and bottom of the formula ? It takes a large space here. –  user995434 Jul 1 '12 at 0:49
    
@user995434 have a look at the documentation you can change the 'overhang' for example –  cmhughes Jul 1 '12 at 0:51
    
I tried to change the overhang and the number of lines but it does not reduce the space in "top" of the formula –  user995434 Jul 1 '12 at 1:07
    
You can always add extra negative space. Try \lipsum[3] \begin{wrapfigure}[3]{l}{.5\textwidth} \vspace{-\baselineskip} \begin{equation} T_y = \begin{cases} x + \alpha & \text{if $\alpha = \beta$}\ x^2 + \beta & \text{else} \end{cases} \end{equation} \end{wrapfigure} –  mrf Jul 1 '12 at 7:37

@user995434 I think you're looking for \abovedisplayskip; see Herber's Mathmode document –  cmhughes Jul 1 '12 at 14:16
