與目錄相關的問題

Question

由於您的文檔類別amsbook不是標準文檔類別之一，因此最好不要使用titlesec;以下程式碼包含對截面單位的必要重新定義，並且還將在目錄中的數字前面加上符號：

我還更改了鏈接問題中的答案，以不使用titlesec.

最後一點：AMS 文件類別是為提交到 AMS 而設計的，因此它們具有非常具體的設置，正如您所看到的，可能很難覆蓋。

如果您不限於使用其中一個 AMS 類，我建議您切換到另一個文件類；這樣做可能是一筆不錯的交易，因為現在可以使用現有套件（與 AMS 類別不相容）輕鬆完成格式變更。舉個例子，以下面的文件為例，它可以輕鬆地產生格式（在文件和目錄中），也包含一些樣式設定amsbook：

\documentclass{book}
\usepackage[compact]{titlesec}
\usepackage[titles]{tocloft}
\usepackage{chngcntr}

\counterwithout{section}{chapter}

\newlength\mylen
\renewcommand\cftchappresnum{\chaptername~}
\renewcommand\cftchapaftersnum{.}
\renewcommand\cftchapfont{\normalfont}
\renewcommand\cftchappagefont{\normalfont}
\settowidth\mylen{\cftchappresnum\cftchapaftersnum} % extra space
\addtolength\cftchapnumwidth{\mylen}
\renewcommand\cftsecdotsep{\cftnodots}
\renewcommand\cftsecpresnum{\S}
\renewcommand\cftsecaftersnum{.}

\titleformat{\chapter}[display]
