I'm not sure why it is not correct : I guess you mean not correct Org
syntax?
(I broke my example by shortening it, one \end{array} is missing and there
used
to be other arrays below)
The problem as I feel it is that \[ \] works sometimes, but not as often
as with LaTeX,
which is disconcerting.
I know that theparagraph entity in Org mode is different than what it is is
in LaTeX, but still.
Why \[ ... \] couldn't be handled as if it where \begin{equation} ...
\end{equation} ?
Is there any other use of \[ that would prevent its detection ?
Sorry to be such an hassle, but that would help to smooth the conversion of
previous LaTeX files/users
to Org.
If I fix it and I use #+begin_equation ... #+end_equation , I still hit
something with these math delimiters:
#+begin_equation
\begin{array}{c}
\begin{array}{|c|c|c|}
\hline
\delta_{1} & 0 & 1 \\
\hline
p & \{p, q\} & \{q\} \\
\hline
q & \{r\} & \{q, r\} \\
\hline
r & \{s\} & \{p\} \\
\hline
s & \{s\} & \{p\} \\
\hline
\end{array}
\vspace{1em} \\
(\{p,q,r,s\}, \{0,1\}, \delta_{2}, p, \{q,s\})
\end{array}
#+end_equation
The last line but two is translated :
(\{p,q,r,s\}, \{0,1\}, $\delta$$_{\text{2}}$, p, \{q,s\})
This time, given that we are in an equation environment, things should be
left as-is surely?

True, didn't notice that it could make a difference, because Org-mode
refuses to indent it.
I mean I used <Tab> on all lines and thought that it wasn't indented
because it could have
been the previous line that was wrapped. Org-mode is able to indent the
second line but
what is preventing it to indent the third line?

Ok. I understand that curly braces in plain text need to be backslahed in
LaTeX.
But again what is surprising is that the backslash itself
in \IEEEAuthorBlockA and \IEEEAuthorBlockN are not translated to LaTeX
syntax.
Actually, it is only the second curly brace that gets backslashed, not even
the first
one.

I hope my comments do not seem too rude. I try to report the feeling of
someone
who doesn't know the internals. I think that the less suprised the user is,
the more it is
willing to accept the tool. In the area of maths delimiters, I start to
wonder if Org-mode doesn't push too far
its guessing of what the user had intended. But maybe I don't see the whole
picture.
Thanks a lot for your help and your work,
