Numbering of Theorem/Lemma

Question

I have some lemma (let's call it lemma 4) in my main text, but I prove it in the appendix. Therefore, I want to restate the lemma in the appendix again as lemma 4. How can I achieve this?

Thanks!

Could you add a minimal example code? – Apr 26 '19 at 08:07 — , Apr 26 '19 at 08:07

One way would be to use the thm-restate package which is part of thmtools. See for example the answer to this question.

You can use the thm-restate package of thmtools:

\documentclass{article}

\usepackage{thmtools}
\usepackage{thm-restate}

\declaretheorem{Lemma}

\begin{document}

\section{First}    
\begin{restatable}{Lemma}{lemmfour}
    \label{lemm:4}
    Content of Lemma~4.
\end{restatable}


\section{Second}
\lemmfour*

\end{document}
