# AMS article section headings in sans-serif

I want to produce an AMS article document using only a sans-serif font. The following almost achieves this:

\documentclass{amsart}
\renewcommand{\familydefault}{\sfdefault}

...


However, section headings are still typeset in roman. How can I get also the section headings in the standard sans-serif font?

Your problem is that the class does

\def\section{\@startsection{section}{1}%
\z@{.7\linespacing\@plus\linespacing}{.5\linespacing}%
{\normalfont\scshape\centering}}


and the default font set does not have small caps sans serif. If you want sans serif you either need to change fonts or disable small caps

 \let\scshape\relax


is a blunt instrument, but probably effective in this case.

Thanks. I would be happy with this as long as I could make the section headings a bit bigger. –  Bok Mal Jul 27 '12 at 14:13
well copy the definition I show and change \normalfont to \large or \Huge or whatever (and same for the other headings) you will find the definitions in amsart.cls –  David Carlisle Jul 27 '12 at 15:03
