# Amsart: footnote for the author

Assume the following code:

    \usepackage{amssymb}
\usepackage{graphicx}   % if you want to include graphics files
\usepackage{amsmath}
\usepackage{amsthm}\begin{document}

\begin{document}

% author information

% first author

\author{Author 1}
\email{email 1}

% second author

\author{Author 2}

% the address where the research was carried out

% current address, usually not needed because it is the same as the

\email{email 2}

% title

\title{Title}
\end{document}


How can I set a footnote to the authors (1 the the first and 2 to the second), such that at the end of the paper the number indicates which email address belongs to which author? For short I would like to have something like: Author 1^1 and at the end ^1 Email-address: email_1.

You can use the optional argument to \address or to \email

\documentclass{amsart}
\begin{document}
% author information
% first author
\author{Author 1}
\email{email 1}

% second author
\author{Author 2}

• What if there are three authors from University 2 and you want to use one footnote for all three? You can't do like \address[this, that and the other]{University 2}. – Untitled Jul 12 '16 at 11:16
• What I meant was that (this, that and the other) looks too big for a label. I prefer something more like a dagger, small. Do you think that can be done in amsart? – Untitled Jul 13 '16 at 17:50
• @Untitled The amsart class prints the information about the authors at the very end, so symbols would refer to something quite far away. – egreg Jul 13 '16 at 17:52
