[Tex/LaTex] Make amsart section titles in article document class

amsartarticletitlesec

I like the section titles in the amsart document class.

Is it possible to have a standard article, but the section titles from the amsart document class?

I have looked at titlesec package, but I do not know how to find the style of the section titles from the amsart document class.

Here is a solution using the titlesec package. Add the following lines to your preamble to mimic the section headings of the amsart class.

\usepackage[indentafter]{titlesec}
\titleformat{name=\section}{}{\thetitle.}{0.8em}{\centering\scshape}
\titleformat{name=\subsection}[runin]{}{\thetitle.}{0.5em}{\bfseries}[.]
\titleformat{name=\subsubsection}[runin]{}{\thetitle.}{0.5em}{\itshape}[.]
\titleformat{name=\paragraph,numberless}[runin]{}{}{0em}{}[.]
\titlespacing{\paragraph}{0em}{0em}{0.5em}
\titleformat{name=\subparagraph,numberless}[runin]{}{}{0em}{}[.]
\titlespacing{\subparagraph}{0em}{0em}{0.5em}

As a comparison, here is a sample document typeset with the article class and the titlesec package on the one hand and with the amsart class on the other one.

The code for the document with article+titlesec:

\documentclass{article}
\usepackage[indentafter]{titlesec}
\titleformat{name=\section}{}{\thetitle.}{0.8em}{\centering\scshape}
\titleformat{name=\subsection}[runin]{}{\thetitle.}{0.5em}{\bfseries}[.]
\titleformat{name=\subsubsection}[runin]{}{\thetitle.}{0.5em}{\itshape}[.]
\titleformat{name=\paragraph,numberless}[runin]{}{}{0em}{}[.]
\titlespacing{\paragraph}{0em}{0em}{0.5em}
\titleformat{name=\subparagraph,numberless}[runin]{}{}{0em}{}[.]
\titlespacing{\subparagraph}{0em}{0em}{0.5em}
\usepackage{blindtext}
\begin{document}
\section{First section (article with titlesec)}
\blindtext
\subsection{First subsection}
\blindtext
\subsubsection{First subsubsection}
\blindtext
\paragraph{First paragraph}
\blindtext
\subparagraph{First subparagraph}
\blindtext
\end{document}

The code for the amsart class:

\documentclass{amsart}
\usepackage{blindtext}
\begin{document}
\section{First section (amsart)}
\blindtext
\subsection{First subsection}
\blindtext
\subsubsection{First subsubsection}
\blindtext
\paragraph{First paragraph}
\blindtext
\subparagraph{First subparagraph}
\blindtext
\end{document}

[Tex/LaTex] Changing the section title style for an article document type

The titlesec package or secsty might have the resources you need.

If it's a longer project, look at the memoir document class, which has more options, but will involve more work to conform to university guidelines.

Here's a very quick sectsty version of what you want.

\usepackage{sectsty}
\sectionfont{%
\sectionrule{2ex}{1pt}{-1ex}{1pt}%
}

And to do roughly the same thing with titlesec do the following:

\usepackage{titlesec}
\titleformat{\section}
  {\titlerule%
  \normalfont\bfseries\Large}
  {\thesection}{1em}{}[\titlerule]

I think I prefer the titlesec version, because titlesec is a better overall package, in my opinion. If you want to change the thickness of the titlerules here, the second one breaks if you add an argument to it. So put \newcommand{\trule}{\titlerule[1pt]} or whatever thickness you want between the \usepackage and the \titleformat commands. Then replace each \titlerule with \trule.

As for a memoir version? Work it out yourself! The memoir documentation is excellent.

[Tex/LaTex] Keywords and MSC Classification in LaTeX article class

The amsart commands are defined to create commands \@keywords and \@subjclass, which are then used to typeset footers in the \maketitle command. You could hack the \maketitle command provided by the article class (or even better, redefine it in a class of your own) to provide similar functionality, but it's easier (and sloppier) to hack the \@title command:

\makeatletter
\newcommand{\subjclass}[2][1991]{%
  \let\@oldtitle\@title%
  \gdef\@title{\@oldtitle\footnotetext{#1 \emph{Mathematics subject classification.} #2}}%
}
\newcommand{\keywords}[1]{%
  \let\@@oldtitle\@title%
  \gdef\@title{\@@oldtitle\footnotetext{\emph{Key words and phrases.} #1.}}%
}
\makeatother

These definitions are very hacky and likely require correct ordering of things (and as I said you really should either hack the \maketitle command properly or extend article with your own class). Most importantly, use \keyword and \subject after \title. But it works.
