[Tex/LaTex] How to position the paper’s authors’ addresses on the front page (maketitle)

titles

When I use the following code for the title page of a paper (please see below), the authors' addresses and emails appear on the last page of the paper. However I need them to appear on the first-title page (after the authors' names before the abstract). How can I do this?

\documentclass [reqno, 12pt ]{amsart}
...
\begin{document}

\title[paper]{Nice paper}

\author{Me}
\address{University}
\email{mmm@lala.com}

Best Answer

changing the positioning of addresses in amsart is nontrivial.

here i have adapted the code used for an existing journal that has a style similar to what has been requested. the result is not perfect; for one author, the address is placed on a separate line, but for more than one author, the addresses are strung out after the associated author name. i haven't analyzed this sufficiently to determine how long it would take to change robustly, but i have run out of time.

i hope this is useful.
