I have a question about the numbering in the appendix.

I want to proof a Lemma in the appendix which I used in the normal sections of my thesis. Therefore, I want to state the Lemma again in the appendix, followed by the proof. But I would like to keep the numbering of the Lemma the same as where I first used it instead of having them numbered with (A.1) etc.


In the normal chapters:

Lemma 3.7

statement and formular (3.21)

Then in the Appendix it should also stay like this:


Lemma 3.7



In order to proof equation (3.21), we have to....

\end proof

I hope it is clear, what I'm looking for.

    See tex.stackexchange.com/questions/422/…, but there is another question here which can restate the environment completely. I'm on mobile and cannot find it. (And welcome to TeX.SX!) Nov 18 '13 at 13:47

    You can use a stared version of the \newtheorem and change its theoremstyle to format in the same way. Then you can use \begin{lemaX}[Lemma~\ref{lema3.7}] \end{lemaX}.

I use this commands and it works for me:

\newcommand{\seepage}[1]{\marginpar{\scriptsize (p.~\pageref{#1})}}
\item[] \textbf{Lemma~\ref{#1}.} \seepage{#1} \em}{\end{trivlist}}

I hope that this helps

  • Welcome to TeX.SX! A tip: If you indent lines by 4 spaces, they'll be marked as a code sample. You can also highlight the code and click the "code" button (with "{}" on it). Additionally, explaining a bit more about how this works and/or giving a complete MWE might be helpful.
