# Numbering in revtex4

I use revtex for my paper, and the sections are numbered as I. II. (roman), but when I use \numberwithin{equation}{section}, I get sth like (I.1), but I'd like it to be like (1.1), I looked around but didn't find anything to change it...

So if anybody can help, I'd appreciate it :)

In the revtex4 class sections are numbered with Roman numerals; I don't think it's a good idea using two different representations for the same number. –  egreg Jan 20 '13 at 22:59
How come? It just looks nicer this way imo... –  dingo_d Jan 20 '13 at 23:02
Your readers may be puzzled about what the first number means, since they are in "Section I" and not in "Section 1". –  egreg Jan 20 '13 at 23:12
Dunno, I don't think that will confuse the readers (not that it will be many of them since it's for a seminar, and I kinda think that only my mentor and professors in charge of the seminar will read it :) –  dingo_d Jan 21 '13 at 10:41

\documentclass{revtex4-1}
\usepackage{amsmath}
\numberwithin{equation}{section}
\renewcommand\theequation{\arabic{section}.\arabic{equation}}
\begin{document}

\section{aaa}

$$$$1=2$$$$

\section{aaa}

$$$$1=2$$$$

\end{document}

Jup, that seems to does the trick :) –  dingo_d Jan 20 '13 at 22:56
