將 \chapter 導入 amsart

Question

我想建立一個文檔的外觀amsart，但添加了\chapter命令（樣式與amsbook或不同）。我怎樣才能做到這一點？

我試圖讓 LaTeX 通過 和 的各種組合來加載和，amsbook但這似乎是一個失敗的策略，因為它們都使用 定義了很多東西，導致了無限的錯誤。我還意識到我不能反過來做，因為我想堅持定理的外觀，如 in和 not in 。我也知道，理論上我可以使用 自己設計樣式，但是要獲得 標題的間距需要大量的手動工作，並且我想避免手動執行此操作。amsart\LoadClass\documentclass\newcommandamsartamsbooktitlesecamsart

MWE 如下：

%\documentclass[openany,11pt]{amsbook}
\documentclass[11pt]{amsart}

\newtheorem{lemma}{Lemma}[chapter]
\newtheorem{theorem}[lemma]{Theorem}

\begin{document}

\chapter{My Fair Chapter}

\section{Lovely section}

\begin{theorem} % Should show "Theorem" in bold, unintended.
I love ducks.
\end{theorem}

\end{document}

Answer 1

amsbook.cls我會改變你不喜歡的部分。僅添加章節的基礎結構所需的程式碼行比 David Carlisle 新增的程式碼行多得多，因為也應考慮目錄和其他清單。

\documentclass{amsbook}
\usepackage{etoolbox}

\makeatletter
\numberwithin{section}{chapter}
\def\@secnumfont{\mdseries}
\def\section{\@startsection{section}{1}%
  \z@{.7\linespacing\@plus\linespacing}{.5\linespacing}%
  {\normalfont\scshape\centering}}
\def\subsection{\@startsection{subsection}{2}%
  \z@{.5\linespacing\@plus.7\linespacing}{-.5em}%
  {\normalfont\bfseries}}

\patchcmd{\@thm}{\let\thm@indent\indent}{\let\thm@indent\noindent}{}{}
\patchcmd{\@thm}{\thm@headfont{\scshape}}{\thm@headfont{\bfseries}}{}{}

\makeatother

\newtheorem{thm}{Theorem}[section]

\begin{document}

\chapter{Chapter title}

\section{Title of this section}
\subsection{Title of this subsection}

\begin{thm}
Whatever the theorem says.
\end{thm}

\begin{thm}[Somebody]
Whatever the theorem says.
\end{thm}

\end{document}

\chapter{Chapter title}這是如果我刪除、自訂並加載時得到的結果amsart。

Answer 2

\chapter只需複製與from amsbook相關的行

%\documentclass[openany,11pt]{amsbook}
\documentclass[11pt]{amsart}

\makeatletter

\def\chaptermark#1{}%whatever


\let\chapterrunhead\partrunhead

\def\chapter{%

  \ifnum\c@secnumdepth<\z@ \let\@secnumber\@empty
  \else \let\@secnumber\thechapter \fi
  \typeout{\chaptername\space\@secnumber}%
  \def\@toclevel{0}%
  \ifx\chaptername\appendixname \@tocwriteb\tocappendix{chapter}{#2}%
