我想拥有标题中有粗体数学符号，但目录中没有我选择了 Bernard 的解决方案，titlesec该文档已经大量使用了该解决方案。除了二问题：
——我无法让它为章节工作，因为\titleformat*{\chapter}{\bfseries\boldmath}会导致错误。
--我认为，章节标题的大小现在已经缩小到，tiny添加\big会导致错误。
（一小时前，我又收到了第三个，但那是因为我看不懂！）
我认为这个问题因我拥有的所有参考机制而变得复杂。因此，这里是 MWE 中的内容。

答案1
主要问题是\titleformat*不能应用于\chapter。您可以改为修补\@makechapterhead和\@makeschapterhead，实际上是 定义的它们的别名titlesec。此外，您需要说明 的字体大小\section。

答案2
为了进一步阐述我的评论，我补充一下
\makeatletter
\g@addto@macro\bfseries{\boldmath}
\makeatother
您的代码不会产生错误，并且在您要求文本加粗时使数学变为粗体：
（完整文档代码如下。）
当然，应该谨慎使用它，因为人们需要决定如果数学已经包含单个\mathbf符号应该怎么做，但你自己的尝试也有类似的警告。
正如我在评论中所说，尺寸问题等是单独的问题。
