I needed something equivalent with \begin{equation} and also stuff like
\begin{equation}
\left\{
\begin{array}{cc}
\partial_t \eta _{prey} (t) =&  a \eta _{prey} - a \varphi _{meet} \\
\partial_t \eta _{pred} (t) =&  -c \eta _{pred} + c \varphi _{meet} \nonumber\\
\end{array}
\right.
\end{equation}

I found a very nice book about TeX. "Tex for the Impatient", one of the 
authors being Karl! It was not so easy to find, but then I found in a few 
minutes the high level constructs I needed:

$$\eqalign

and

$$\left\{\eqalign{ ...

I find those very handy to use. I was first a bit impressed by a mail you 
send with
$$
\vbox{
  \hbox{$a = \min(S_1,\ldots,S_n)$}
  \medskip
  \hbox{$b = \max(S_1+D_1,\ldots,S_n+D_n)$}
  \medskip
  \hbox{$R_{ij} = \cases{ R_j, &if $S_j \leq i < S_j+D_j$\cr
                  0, &otherwise}$}
}
$$
but ready to learn. In the end I didn't had to.

Strangely it seems that latex2html don't handle constructs with \eqalign 
right.
