我正在处理以下问题。我的书中的一个小节的名称太长，无法放入目录中。有人能建议在目录中插入换行符的解决方案吗？
这是我的代码的一部分：
\documentclass[11pt,a4paper]{book}
\usepackage[utf8]{inputenc}
\usepackage[T1,T2A]{fontenc}
\usepackage[english,russian]{babel}
\usepackage{indentfirst}
\usepackage{misccorr}
\usepackage{graphicx}
\usepackage{latexsym}
\usepackage{cmap}
\usepackage{blindtext}
\usepackage{hyperref}
\usepackage[resetlabels,labeled]{multibib}
\begin{document}
\chapter{Additions}
\section{The Applications of Induced Representations}
\subsection[Normal Divisors and Applications to Powers of \protect\linebreak Irreducible Representations]{Normal Divisors and Applications to Powers of Irreducible Representations}
%The problem is in this particular line
