我只想显示我的方法的名称，后面跟着一些方程式和项目，但是我出现了这个错误：
! Missing \endgroup inserted.

因此我想问一下有什么方法可以实现它吗？
答案1
为了itemize在节点中使用类似的东西，您需要使用类似 的选项text width。下面的方法有效，但输出肯定还有一些改进的空间。如果你给我提示，我可能会尝试帮助你实现更好的输出。有一件事很难不被注意到，那就是你正在加载smartdiagram但没有使用它。相反，你正在使用和覆盖这个不错的包（例如 satellite）中的样式。

如果你想利用smartdiagram，你可以（再次）“破解”它（这里的一些元素来自这里）。
\documentclass{beamer}
\usepackage{smartdiagram}
\smartdiagramset{%

planet text width=2cm,
planet font= \normalsize,
satellite size=1.5cm,

distance planet-satellite=3.2cm,
/tikz/connection planet satellite/.append style={<->}
}

当然，如果所有卫星都很庞大，你可以使用例如这个答案作为动画版本的起点。
