为什么摘要没有显示在第 2 页？

Question

我为我的文档添加了标题页，之后我发现摘要消失了。我编写的代码如下：

\documentclass[10 pt,a4paper,twoside,reqno]{amsart} 
\usepackage{amsfonts,amssymb,amscd,amsmath,enumerate,verbatim,calc} 
\renewcommand{\baselinestretch}{1.2} 
\textwidth = 12.5 cm 
\textheight = 20 cm 
\topmargin = 0.5 cm 
\oddsidemargin = 1 cm 
\evensidemargin = 1 cm 
\pagestyle{plain} 
\newtheorem{theorem}{Theorem}

\newtheorem{definition}{Definition}
\begin{document}
\begin{titlepage}
\vfill
\centering
{\Huge On the Reflection Property of a Pararbolid}\\[1cm]
{\Large Shrey Aryan}\\[0.6cm]
XYZ Department, ABC University

Email:[email protected]
\vfill
\end{titlepage}

\begin{abstract}
 Some Text....
 \end{abstract}

 Keywords: Paraboloid, Partial Differential Equations, Reflection. (35E02)


\section{Introduction}
 Some Text...

\end{document}

标题页看起来没问题，但在下一页上我只能看到显示的关键词。我想在第 2 页显示摘要，但不知何故，当我单击“快速构建”时它没有出现。为什么会发生这种情况？

Answer 1

标题页看起来amsart会像这样（左侧）：

\documentclass[10 pt,a4paper,twoside,reqno,titlepage]{amsart} 
\usepackage{blindtext} 
\begin{document}
\title{On the Reflection Property of a Pararbolid}
\author{Shrey Aryan}
\address{Wombat Department, Capybara  University}

\email{:[email protected]}

\begin{abstract}
This Abstract does not contain any Wombats. I am not happy.
\blindtext
\end{abstract}

\keywords{ Paraboloid, Partial Differential Equations, Reflection. (35E02)}

\maketitle

\section{Introduction}
\blindtext

\end{document}

如果您想要完全控制，请自己模拟抽象环境。

\documentclass[10 pt,a4paper,twoside,reqno]{amsart} 
\usepackage{blindtext} 
\begin{document}
\begin{titlepage}
    \vfill
    \centering
    {\Huge On the Reflection Property of a Pararbolid}\\[1cm]
    {\Large Shrey Aryan}\\[0.6cm]
    Wombat Department, Capybara University

    Email:[email protected]
    \vfill
\end{titlepage}

\begin{quote}
    \textsc{Abstract:}
This Abstract does not contain any Wombats. I am not happy.
\blindtext
\end{quote}
