beamer：定理、例子、定义和引理的不同编号

Question

我想对定理、例子、定义和引理使用不同的编号。我在序言中使用以下代码

\setbeamertemplate{theorem}[ams style]
\setbeamertemplate{theorems}[numbered]

此代码运行良好，但定理和其他环境的编号连续。如果您能指导我如何在 中为定理、示例、定义和引理获取不同的编号，我将不胜感激beamer。

Answer 1

beamer使用选项加载notheorems并“手动”声明所有定理类型，而不引入通用编号方案。（注意：这有点像 hack，因为它会破坏countsect除 之外的每种类型的包选项 [按节进行定理编号] theorem。）

\documentclass[notheorems]{beamer}

\setbeamertemplate{theorem}[ams style]
\setbeamertemplate{theorems}[numbered]

\makeatletter
    \ifbeamer@countsect
      \newtheorem{theorem}{\translate{Theorem}}[section]
    \else
      \newtheorem{theorem}{\translate{Theorem}}
    \fi
    \newtheorem{corollary}{\translate{Corollary}}
    \newtheorem{fact}{\translate{Fact}}
    \newtheorem{lemma}{\translate{Lemma}}
    \newtheorem{problem}{\translate{Problem}}
    \newtheorem{solution}{\translate{Solution}}

    \theoremstyle{definition}
    \newtheorem{definition}{\translate{Definition}}
    \newtheorem{definitions}{\translate{Definitions}}

    \theoremstyle{example}
    \newtheorem{example}{\translate{Example}}
    \newtheorem{examples}{\translate{Examples}}
