如何保持不同幻灯片中的词干编号相同？

Question

我使用的是 beamer 表示法。我想让引理的编号在不同的幻灯片中保持不变。我不想在不同的幻灯片中对同一个引理重新编号

\documentclass{beamer}

%\usetheme{Boadilla}
\usetheme{Madrid}
\usepackage{bibentry}
\usepackage[linesnumbered,ruled,vlined]{algorithm2e}
\setbeamertemplate{theorems}[numbered]

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[backend=biber]{biblatex}

% Removes icon in bibliography
\setbeamertemplate{bibliography item}{}

\begin{document}

\begin{frame}
\titlepage
\end{frame}

\frame{\frametitle{Outline}
\begin{lemma}
  If $d$ is a $a$ then it is 
\end{lemma}
}

\frame{\frametitle{}
\begin{lemma}
  If $d$ is a $a$ then it is 
\end{lemma}
\begin{proof}
  wfmkrf
\end{proof}
}

\end{document}

看到相同的引理得到不同的数字

Answer 1

欢迎使用 TeX-SE！恕我直言，没有必要使用两张幻灯片，\pause就足够了，如果您真的只想在第一帧上显示标题，请使用\frametitle<1>{Outline}。

\documentclass{beamer}
\usetheme{Madrid}
\setbeamertemplate{theorems}[numbered]

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}


\begin{document}

\begin{frame}
\titlepage
\end{frame}

\begin{frame}
\frametitle<1>{Outline}
\begin{lemma}
  If $d$ is a $a$ then it is 
\end{lemma}
\pause
\begin{proof}
  wfmkrf
\end{proof}
\end{frame}


\end{document}

如果你真的想要记住旧值，给你。

\documentclass{beamer}

%\usetheme{Boadilla}
\usetheme{Madrid}
\usepackage{bibentry}
\usepackage[linesnumbered,ruled,vlined]{algorithm2e}
\setbeamertemplate{theorems}[numbered]

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[backend=biber]{biblatex}

% Removes icon in bibliography
\setbeamertemplate{bibliography item}{}
\newcounter{oldlemma}
\newcounter{storethm}
\begin{document}

\begin{frame}
\titlepage
\end{frame}

\begin{frame}
\frametitle{Outline}
\begin{lemma}\label{lemma1}
  If $d$ is a $a$ then it is 
\end{lemma}
\setcounter{oldlemma}{\number\value{theorem}}
\end{frame}

\begin{frame}
\frametitle{Another lemma}
\begin{lemma}
  If $c$ is a $b$ then it is 
\end{lemma}
\end{frame}

\begin{frame}
\frametitle{}
\setcounter{storethm}{\number\value{theorem}}
\setcounter{theorem}{\numexpr\number\value{oldlemma}-1}
\begin{lemma}{\number\value{oldlemma}}
  If $d$ is a $a$ then it is 
\end{lemma}
\begin{proof}
  wfmkrf
\end{proof}
\setcounter{theorem}{\number\value{storethm}}
\end{frame}

\begin{frame}
\frametitle{Yet another lemma}
\begin{lemma}
  If $f$ is a $g$ then it is 
\end{lemma}
\end{frame}

\end{document}

Answer 2

我会将引理和证明放在一张带有叠加层的幻灯片上，并在第二张子幻灯片上显示证明。

\documentclass{beamer}
\usetheme{Madrid}
\setbeamertemplate{theorems}[numbered]
\begin{document}
\frame{\frametitle{Outline}
\begin{lemma}
  If $d$ is a $a$ then it is 
\end{lemma}
\onslide<2>{%
\begin{proof}
  wfmkrf
\end{proof}
}}
\end{document}

Answer 3

每次开始新框架时都会重置引理编号。

顺便说一句，找到词干和框架的反名并不容易。

\documentclass{beamer}

%\usetheme{Boadilla}
\usetheme{Madrid}
\usepackage{bibentry}
\usepackage[linesnumbered,ruled,vlined]{algorithm2e}
\setbeamertemplate{theorems}[numbered]

%\usepackage[utf8]{inputenc}% not with my editor
%\usepackage[T1]{fontenc}% I would rather not use XeLaTeX
\usepackage[backend=biber]{biblatex}

% Removes icon in bibliography
\setbeamertemplate{bibliography item}{}

\counterwithin*{theorem}{framenumber}% added command

\begin{document}

\begin{frame}
\titlepage
\end{frame}

\frame{\frametitle{Outline}
\begin{lemma}
  If $d$ is a $a$ then it is 
\end{lemma}
}

\frame{\frametitle{}
\setcounter{theorem}{0}
\begin{lemma}
  If $d$ is a $a$ then it is 
\end{lemma}
\begin{proof}
  wfmkrf
\end{proof}
}

\end{document}
