我正在使用amsthm包和thmtools包來格式化我的手稿。
我在定理內對註釋進行編號，也就是說，備註 2.1。,備註 2.2。等等之後定理2。然而，之後只發表一句話時，比如說，定理1，我希望它可以編號為備註 1.代替備註1.1。
numbered=unless unique透過使用中的選項thmtools，可以完全消除編號，得到評論。這不是我真正想要的，因為我希望以後可以通過編號方便地引用該評論，而不是說“定理1之後的評論」。
下面是一個 MWE，我被困住了，想知道是否有任何快速的適應來實現我的目的。預先感謝您提供可能的解決方案。
\documentclass{article}
\usepackage{amsthm}
\usepackage{thmtools}
\newtheorem{thm}{Theorem}
\theoremstyle{remark}
\declaretheorem[numberwithin=thm, name=Remark, numbered=unless unique]{rmk}
\begin{document}
\begin{thm}
This is a theorem.
\end{thm}
\begin{rmk} % only one remark made
This is the only remark, so number it the same as the previous theorem.
What I want is Remark 1., instead of Remark. or Remark 1.1.
\end{rmk}
\begin{thm}
This is the second theorem.
\end{thm}
\begin{rmk} % Multiple remarks
Multiple remarks follow, and this is the first.
\end{rmk}
\begin{rmk}
Since there are multiple remarks made, all of them are numbered.
\end{rmk}
\begin{rmk}
The style is Remark 2.1., 2.2., and 2.3., etc.
\end{rmk}
\end{document}
答案1
您可以使用該套件“手動”定義您想要的行為unique。下面只是模擬了thmtools的作用numbered=unless unique，但不是將註釋設為唯一（如果唯一），而是將其\thermk設為\thethm。
\documentclass{article}
\usepackage{amsthm}
\usepackage{thmtools}
\usepackage[unq]{unique}
\newtheorem{thm}{Theorem}
\theoremstyle{remark}
\declaretheorem[numberwithin=thm, name=Remark]{rmk}
\addtotheorempreheadhook[rmk]{%
\setuniqmark{rmk.\thethm}%
\ifuniq{rmk.\thethm}
{\def\thermk{\thethm}}
{}%
}
\begin{document}
\begin{thm}
This is a theorem.
\end{thm}
\begin{rmk} % only one remark made
This is the only remark, so number it the same as the previous theorem.
What I want is Remark 1., instead of Remark. or Remark 1.1.
\end{rmk}
\begin{thm}
This is the second theorem.
\end{thm}
\begin{rmk} % Multiple remarks
Multiple remarks follow, and this is the first.
\end{rmk}
\begin{rmk}
Since there are multiple remarks made, all of them are numbered.
\end{rmk}
\begin{rmk}
The style is Remark 2.1., 2.2., and 2.3., etc.
\end{rmk}

定義具有相同效果的鍵並不太難。
\documentclass{article}
\usepackage{amsthm}
\usepackage{thmtools}
\makeatletter
\define@key{thmdef}{uniquewithparent}{%
\setkeys{thmdef}{parent=#1}
\RequirePackage[unq]{unique}
\addtotheorempreheadhook[\thmt@envname]{%
\setuniqmark{\thmt@envname.\csname the#1\endcsname}%
\ifuniq{\thmt@envname.\csname the#1\endcsname}
{\@xa\def\csname the\thmt@envname\endcsname{\csname the#1\endcsname}}
{}%
}
}
\makeatother
\newtheorem{thm}{Theorem}
\declaretheorem[uniquewithparent=section]{lemma}
\theoremstyle{remark}
\declaretheorem[name=Remark,uniquewithparent=thm]{rmk}
\begin{document}
\section{A section}
\begin{lemma}
Some text.
\end{lemma}
\begin{thm}
This is a theorem.
\end{thm}
\begin{rmk} % only one remark made
This is the only remark, so number it the same as the previous theorem.
What I want is Remark 1., instead of Remark. or Remark 1.1.
\end{rmk}
\begin{thm}

\end{thm}
\begin{rmk} % Multiple remarks

\end{rmk}
\begin{rmk}

\end{rmk}
\section{Another section}
\begin{lemma}
More text.
\end{lemma}
\begin{lemma}
Even more text.

答案2
我們expl3可以將定理後面的註釋數量儲存在屬性列表中（進一步的值將被覆蓋，因此我們獲得最大值）。
運行結束時，這些值將以以下形式寫入 aux 檔案中
\rmklist{1=1,2=3,1=1,}
（範例中的值），因此在下一次運行開始時，我們可以填入用於檢查的另一個屬性清單。如果儲存的數字大於 1，.\arabic{rmk}則使用。
\documentclass{article}
