可恢復不顯示定理編號

Question

我從那裡了解到可恢復的這回答。然而，當我把定理放在附錄時，它的參考文獻沒有編號。這是一個 MWE：

\documentclass{amsart}
\usepackage{thmtools} 
\usepackage{thm-restate}
\newtheorem{theorem}{Theorem}[section]
\usepackage{hyperref}

\begin{document}


\begin{restatable*}{theorem}{thm}
  Everybody knows that $1 + 1 = 2$.
\end{restatable*}

I would like this \ref{thm} to display A.1.

\appendix
\section{Proofs}
\thm\label{thm}
\begin{proof}
  Proof is trivial.
\end{proof}

\end{document}

Answer 1

將其\label{thm}移入restatable*環境：

\documentclass{amsart}
\usepackage{thmtools} 
\usepackage{thm-restate}
\newtheorem{theorem}{Theorem}[section]
\usepackage{hyperref}

\begin{document}


\begin{restatable*}{theorem}{thm}\label{thm} % <<< \label moved to here
  Everybody knows that $1 + 1 = 2$.
\end{restatable*}

I would like this \ref{thm} to display A.1.

\appendix
\section{Proofs}
\thm
\begin{proof}
  Proof is trivial.
\end{proof}

\end{document}
