I have to write things like
f(x) = | 0 if x == 1
| 1 otherwise
with the big curly bracket.
It's a common thing and I found in latex is like here
http://www.mathhelpforum.com/math-help/latex-help/59690-left-curly-brace.html
Using \left{ and \begin{gathered}
For some reasons anyway it doens't work.
This
--8<---------------cut here---------------start------------->8---
$\phi_{sum}(g1))(\bot) = (\phi_{sum}(g2))(\bot) =$ \newline
\begin{gathered}
1 if x < 0 \\
\bot otherwise \\
\end{gathered}
--8<---------------cut here---------------end--------------->8---
doesn't to what I'd like it to do.
Any idea?

No idea, did you try with \begin{cases}...\end{cases} ?
You can also use \left\{...\right followed by an array.

I don't know anything about the gathered environment, but the standard
solutions are the ones that Olivier Schwander suggested. In your case, the
array solution looks like this:
,----
| \documentclass{article}
|
| \usepackage{amsmath}
|
| \begin{document}
| \[
| \phi_{sum}(g1))(\bot) = (\phi_{sum}(g2))(\bot) = \left\{
| \begin{array}{rl}
| 1 & \text{if } x < 0 \\
| \bot & \text{otherwise}
| \end{array}
| \right.
| \]
| \end{document}
`----
This can be found in the published books, but also in the online
"(Not so) Short Introduction to LaTeX" by Tobias Oetiker et al., p.58.

Yes I'm sorry it was OT, I thought that the problem was the org-mode
translation to latex but it wasn't of course.
But I anyway found out that exporting to pdf with \n:t is really a bad
idea.
It doesn't only mess up with the indentation, using \left and \right it
becomes a mess.
Maybe it would be better to disable it completely or put a very big
warning (I don't see it written in the manual).

I think I will just disable the \n option for LaTeX export.
Thanks.
