as explained before, the problem is not that \begin is ``redefined,''
the whole huge LaTeX is not there.  TeXinfo is built over good old
plainTeX.  See eg. The TeXbook for more info how to use it.

As an example, a plain TeX equivalent of the code you posted follows:

$$
\vbox{
  \hbox{$a = \min(S_1,\ldots,S_n)$}
  \medskip
  \hbox{$b = \max(S_1+D_1,\ldots,S_n+D_n)$}
  \medskip
  \hbox{$R_{ij} = \cases{ R_j, &if $S_j \leq i < S_j+D_j$\cr
                  0, &otherwise}$}
}
$$

HTH,
