# Disable/toggle smallcaps in the title

I am using the amsart document class. I want to to change the text in the titles (such as in \author) to be written normally and not in small caps.

• How can I change this globally? That is, so that the text in all titles (\title, \author, \section, and so on) is written without small caps.
• How can I change this locally? That is, only change it in one place. If, for example, I include my email address in the \author field, I don't want it to be written in small caps. Wrapping the text inside \textnormal or \textrm does not work. Wrapping it inside \lowercase works, but I don't consider it a good solution.

A non-answer: in amsart, you should use the \email command to typeset your email address. It is not used inside the \author field but after it. – Jukka Suomela Sep 6 '10 at 19:29

While amsart uses smallcaps for section headings, it actually uses (full) capitals for \author and \title. Note that a title argument given in upper- and lowercase will produce capitals which are all of the same height.

The following MWE redefines the formatting in a way that only affects \author, \title and \section:

\documentclass{amsart}

\usepackage{etoolbox}

\makeatletter
\patchcmd{\@settitle}{\uppercasenonmath\@title}{}{}{}
\patchcmd{\@setauthors}{\MakeUppercase}{}{}{}
\patchcmd{\section}{\scshape}{}{}{}
\makeatother

\begin{document}

\author{Author, A.}
\title{And now for something completely different}
\maketitle

\section{A section}

Some text.

\end{document}

I don't understand why you'd use amsart if you want to customize the style. Using amsart is basically just a way of telling it you want to use AMS style. It doesn't make sense to me to do that, but then deviate so significantly from its style. If it were me, I'd use the regular article class along with the amsmath package for the power of the AMS classes without the style, which will free you up to use, e.g., packages like titling, fancyhdr and titlesec for customizing the title, headers/footers and section headings.

Sure you can redefine some of the class's internals (lockstep tells you how), but it seems like a funny way of proceeding to me.

I can very well understand why people would like to customise amsart slightly. In general, I find amsart much better-looking than article; it's compact, looks professional, and is well-suited for documents with a lot of math – I don't know any other style that comes even close. The AMS style has some idiosyncratic features related to typesetting authors' affiliation, contact information, etc.; however, I think it is much easier to get a usable style by starting with amsart and tweaking slightly than by starting with article and re-doing everything. – Jukka Suomela Sep 6 '10 at 21:33
Well, the thing is, Samuel does seem to want to re-do everything. Anyway, if I want compact, I load the savetrees package. amsart is problematic, because it isn't compatible with a lot of packages. – frabjous Sep 6 '10 at 21:48
I don't understand why starting from amsart would be any different to starting from article. Naturally if it's less work for me to tweak amsart slightly, I would prefer that to massively tweaking article. – Samuel Sep 8 '10 at 15:16
