# \thanks command specific to each author

What is the correct way to have a \thanks command for a specific author ?

I don't want to use \author{auth1 \and auth2} for obvious reasons (i.e. be able to distinguish the authors).

I have tried various options without success. Here is a rather minimal example where the two thanks are not attributed.

\documentclass{amsart}

\begin{document}

\title[short title]{Longtitle}

\author[Auth1]{Surn1 Auth1}

\author[Auth2]{Surn2 Auth2}

\thanks{Network1}

\thanks{Network2}

\maketitle
\end{document}

Did you have a look at the authblk package? –  Jörg Nov 10 '12 at 9:38
@Jörg No -- this question is about amsart, which features a different syntax for \author and \thanks. –  lockstep Nov 10 '12 at 9:41
Looking at the documentation it seems a design decision; you should say \thanks{Author 1 thanks Xyz}. –  egreg Nov 10 '12 at 10:44
The package's documentation (p. 5) states that "Each occurrence [of \thanks] will be printed as an unnumbered footnote at the bottom of the first page of the article." That seems to be happening alright, but no symbolic footnote marks are generated. The lack of footnote markers may be a design decision, as @egreg hypothesizes, or it may be an oversight/bug. –  Mico Nov 10 '12 at 11:40
@Mico -- the usage of \thanks in amsart (and the other ams document classes) is definitely a design decision. the transition from using a footnote marker to no marker appears to have been made during the period 1986-1988 (before the uniform use of tex to produce ams journals). –  barbara beeton Nov 10 '12 at 13:54

the \thanks associated with each author are placed as unnumbered footnotes at the bottom of the first page. it is usual, with this arrangement, to say something like "The first author was supported by ...", etc., so that it is clear which acknowledgement applies to which author.
however, what i see in the example is probably a url, not a normal acknowledgment. for this use, the ams document classes provide the command \urladdr which, as for e-mail addresses, is listed with the regular address; for amsart, this is at the end of the article.
if footnote markers are required, \footnotemark and \footnotetext can be used judiciously to add the markers manually. however, you may have to manually adjust the value of the counter that is used for the markers to get appropriate results, and you will also need to supply "optional" alternates for the author names to avoid having the footote markers appear in running heads.
the arrangement described is a design decision specific to ams article classes; unless the publication to which you are submitting your article requires amsart`, it is possible that a different document class might better match your expectations.
