Removing brackets from the reference

How to use 1. (number followed by dot) format instead of [1] format in bibliography

I'm using the amsart class, and the command \begin{thebibliography} for references.

This puts all the enumerations of references in square brackets, and I want to get rid of this.

That is, I want the references to look like

1. ~~
2. ~~

rather than

[1]. ~~
[2]. ~~

How can this be achieved??

Use \def\@biblabel#1{\@ifnotempty{#1}{#1}}. Of course you need makeatletter — Marco Daniel, Jul 27 '12 at 15:19

@MarcoDaniel You should turn this into a proper answer so that Siyul can accept it. — Alan Munn, Jul 27 '12 at 15:50

The square brackets are added in macro \@cite in class amsart. The following example redefines the macro to omit the brackets.

\documentclass{amsart}

\makeatletter
\CheckCommand*{\@cite}[2]{%
  {%
    \@citestyle[\citeform{#1}\if@tempswa, #2\fi]%
  }%
}
\renewcommand*{\@cite}[2]{%
  {%
    \@citestyle\citeform{#1}\if@tempswa, #2\fi
  }%
}
\makeatother

\begin{document}
References \cite{abc} and \cite{def}.

\begin{thebibliography}{9}
\bibitem{abc} ABC.

\bibitem{def} DEF.

\end{thebibliography}
\end{document}
