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?
