定理环境没有按照预期的方式运行

Question

我正在使用以下内容模板制作海报。

我想要的是使用 amsthm 包提供的定理环境来阐明一个定理。问题是，在文件 beamerthemeconfposter 中定义了某种“结构”，称为块，当我使用

\newtheorem{theo}{Theorem}
...
\begin{theo}
Theorem
\end{theo}

它创建了一个新的块，其标题为“定理”。它没有像通常那样将定理放在新块中。

\begin{theo}
...
\end{theo}

表现得像

\begin{block}{Theorem}
...
\end{block}

我搜索了所有随模板下载的文档，但找不到任何线索。下图（查看“Riemann-Roch 定理”部分）显示了效果（我删除了 main.tex 文件中的图片）

Answer 1

按照课堂beamerposter上的内容beamer，让我们深入了解一下beameruserguide。

在页面中16我们发现：

因此，我们跳到第 12.4 节，Theorem Environments它以

这意味着所有这些环境在 beamer 中都已定义为 overlay-specification-aware。所有这些环境都类似于beamerblocks。如果您不想要它，请noamsthm在中用作类选项beamerposter：

\documentclass[final,noamsthm]{beamer}

\usepackage[scale=1.24]{beamerposter} % Use the beamerposter package for laying out the poster

\usetheme{confposter} % Use the confposter theme supplied with this template

\newtheorem{theo}{Theorem}
