链接回可重述

链接回可重述

我正在使用具有可重述定理的 ntheorem，并且我希望从重述定理到原始定理（可重述定理）有一个链接回（超链接）。MWE：

\documentclass{memoir}
\usepackage{ntheorem}
\usepackage{thm-restate}

\newtheorem{theorem}{Theorem}

\begin{document}

\chapter{One}

\begin{restatable}{theorem}{th}
Blah
\end{restatable}

\chapter{Two}

%Should link back to restatable in Chapter One
%(without extra \ref, but directly within \th*)
\th*

\end{document}

谢谢您的任何提示，谨致问候

以下方法可行。如果您想使用其他定理样式，您也必须对其进行调整：

\documentclass{memoir}
\usepackage{ntheorem}
\usepackage{thmtools,xpatch}
\makeatletter
\xpatchcmd \thmt@restatable{\@xa\protected@edef\csname the#2\endcsname}
                           {\def\thmt@tmp@restatename{#3}\@xa\protected@edef\csname the#2\endcsname}{}{\fail}


\renewtheoremstyle{plain}%
  {\item[\hskip\labelsep \theorem@headerfont ##1\ 
   \ifcsname thmt@tmp@restatename\endcsname 
   \ifthmt@thisistheone ##2\else\ref{thmt@@\thmt@tmp@restatename}\fi
   \else ##2\fi
   \theorem@separator]}%
  {\item[\hskip\labelsep \theorem@headerfont ##1\ 
   \ifcsname thmt@tmp@restatename\endcsname
   \ifthmt@thisistheone ##2\else\ref{thmt@@\thmt@tmp@restatename}\fi
   \else ##2\fi
   \  (##3)\theorem@separator]%
  }
\makeatother
\newtheorem{theorem}{Theorem}
\usepackage{hyperref}
\begin{document}

\chapter{One}

\begin{theorem}
some theorem
\end{theorem}
\begin{restatable}{theorem}{th}
Blah
\end{restatable}

\chapter{Two}

%Should link back to restatable in Chapter One
%(without extra \ref, but directly within \th*)
\th*

\end{document}

如果链接中应包含单词“定理”（或其他），则可以使用以下定理样式：

\renewtheoremstyle{plain}%
  {\item[
   \ifcsname 
        thmt@tmp@restatename\endcsname 
        \ifthmt@thisistheone 
            \hskip\labelsep \theorem@headerfont ##1\ ##2
        \else
            \mbox{\hyperref[thmt@@\thmt@tmp@restatename]{\theorem@headerfont ##1~##2}} 
        \fi
   \else 
        \hskip\labelsep \theorem@headerfont ##1\ ##2
    \fi
   \theorem@separator]}%
  {\item[
   \ifcsname 
        thmt@tmp@restatename\endcsname
        \ifthmt@thisistheone 
            \hskip\labelsep \theorem@headerfont ##1\ ##2
        \else
            \mbox{\hyperref[thmt@@\thmt@tmp@restatename]{\theorem@headerfont ##1~##2}}
        \fi
   \else 
        \hskip\labelsep \theorem@headerfont ##1\ ##2
   \fi
   \  (##3)\theorem@separator]%
  }
