Re: [Orgmode] Big curly bracket

[Nick Dokos]

[This is OT for this list - comp.text.tex is a better venue.  Otoh, the
 reference might be useful to some people here - but unless org-mode
 content can be added, let's make this the end of the thread. Thanks.]

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}
