This file, using the amsbook layout, numbers all results, Theorems, Definitions,
 etc., using 
\begin_inset Formula $(m.n.p)$
\end_inset

 where the 
\begin_inset Formula $m$
\end_inset

 is the chapter number, the 
\begin_inset Formula $n$
\end_inset

 is the section number, and, finally, the 
\begin_inset Formula $p$
\end_inset

 is the result number in that section.
\end_layout

\begin_layout Standard
This can be changed by modifying the layout file, removing the line
