\title{something}

\address{somewhere}


\begin{document}
    %\today
\begin{abstract}

\end{abstract}
\maketitle

\end{document}

我想在上面的文檔類別中使用 \chapter 。它顯示錯誤“未定義的控制序列”。

我嘗試使用報告文檔類。 \usepackage[english]{babel} 上顯示「TeX 容量超出，抱歉[參數堆疊大小=10000]。\usepackage[english]」。如何更改上面的文檔類別以便我可以使用 \chapter、\section 等等？我是否添加了在某些文檔類中不起作用的 \usepakage？

amsart是支援 Journal 樣式的範本之一，請使用amsbook它代替，您可以獲得輸出：
