Missing abstract with amsart class

Question

I'm not very good at LaTeX but I've been using it to write my dissertation. Have just come to the end and trying to format everything correctly. Whenever I try to put my Abstract paragraph into the form \begin{abstract} (writing here) \end{abstract} and click play the whole abstract section just disappears. What am I doing wrong?

\documentclass[12pt]{amsart}

\begin{document}

\begin{abstract}
(my abstract here)
\end{abstract}
\end{document}

Answer 1

The amsart class does some Mysterious Stuff with abstracts: it stores the abstract in a box to be used in the title page. To get it to appear, issue the magic command \maketitle after the abstract.

(It will then complain about a missing \title ... )

\documentclass[12pt]{amsart}


\begin{document}

\begin{abstract}
(my abstract here)
\end{abstract}

\maketitle
Some text
\end{document}

Answer 2

With amsart you need a \maketitle to see the abstract:

\documentclass[12pt]{amsart}
\title{abc}
\author{author}
\begin{document}

\begin{abstract}
(my abstract here)
\end{abstract}

\maketitle
\end{document}
