.toc(目录)错误

.toc(目录)错误

我正在使用以下模板撰写论文。

\documentclass[11pt,twoside]{book}
%\date{\today}
\begin{document}    
    \tableofcontents
    \chapter{something}
    \subsection{{$p: \underline{X}\rightarrow \mathcal{D}$} is an atlas for {$\mathcal{D}$}} 
    \subsection{Proof that $p: X\rightarrow \mathcal{D}$ is an epimorphism of stacks}
\end{document}

由于某种原因,当我运行该文件时,出现 4 个错误。

\contentsline {subsection}{\numberline {2.3.3}Proof that $p\penalty \@M \mskip 2mu\mathpunct {}\nonscript \mkern -\thinmuskip {:}\mskip 6muplus1mu\relax \relax $\@@underline {\hbox {X}}\mathsurround \z@ $\relax \rightarrow \mathcal {D}$ is an epimorphism of stacks}{71}{subsection.2.3.3}
\contentsline {subsection}{\numberline {2.3.4}$p\penalty \@M \mskip 2mu\mathpunct {}\nonscript \mkern -\thinmuskip {:}\mskip 6muplus1mu\relax \relax $\@@underline {\hbox {X}}\mathsurround \z@ $\relax \rightarrow \mathcal {D}$ is an atlas for $\mathcal {D}$}{73}{subsection.2.3.4}

我在小节中写了以下内容

 "\subsection{Proof that $p\colon \underline{X}\ra \mc{D}$ is an epimorphism of stacks}" and "\subsection{$p\colon \underline{X}\ra \mc{D}$ is an atlas for $\mc{D}$}" 

我该如何修复此错误?这是在 thesis.toc 中

答案1

我用的是旧版本。

\protect\underline而不是仅仅\underline解决问题。
