Unable to use \thanks for one author

Question

EDIT 2: My question was indeed a duplicate or otherwise clouded in some of my own misunderstanding. Apologies for the inconvenience.

EDIT: This question was closed as a duplicate, but the thread linked does not solve my problem. My issue is that I cannot put any sort of \thanks, \footnote, or even \footnotemark inside of the second argument of \author. Also, I am not adding a URL. I am adding text.

I am struggling to add a \thanks to the second author (which should go at the bottom of the first page). In the following, the only thing that's missing is (a) a number/symbol for the second author, and (b) a number/symbol for the footer that \thanks creates. Putting thanks inside the second author full name threw an error. I also tried \footnote, but didn't manage to make it work.

\documentclass[a4paper,11pt]{amsart}
\usepackage{amsmath,amssymb,amsthm, amsfonts,color}

\begin{document}

\title{A paper}

\author[F. Author]{First Author}
\author[S. Author]{Second Author}\thanks{for all the fish}
\address{the department\\
a place}
\email[F. Author]{[email protected]} 
\email[S. Author]{[email protected]}



\maketitle

\begin{abstract}
the abstract
\end{abstract}

\section{intro}
lots of good stuff 

\end{document}

Hopefully this is easy to solve. Thanks in advance!

Answer 1

It may not be desirable to identify exactly which author was given a specific grant or is thanking their sponsor. It may be more diplomatic to Say

The Authors would both like to thank AMS for their generous support of this published article

\documentclass[11pt]{amsart} % A-M-S-ART-icle 
% Templates and template classes are built with ONE prime
% purpose, that is they serve to provide a like it or not framework. 
% ``As author, you are responsible for the content of your paper. 
% At the production end, the concern is to turn the (electronic)
% manuscript into a published document in the style of the designated journal
% see http: //mirrors.ctan.org/info/amscls-doc/Author_Handbook_Journals.pdf

% Unmarked, unnumbered footnotes on the first page of an article should include
% primary classification numbers according to the 2010 Mathematics Subject 
% Classification scheme (www.ams.org/msc) (required);  grant information (optional);
% and key words and phrases describing the subject matter of the article (optional). 

% Formatting is automatic when using the AMS style files. 

% That framework may be upset by the use of package
% contents in a different order or subsequent changes
% to that envisioned by the template writers at the time.
% Item sequencing or structure should not be changed.
% to check what can be here and in what order consult
% the documentation. If you add an item to a template 
% it is your responsibility to change one item at a time
% for comparability.
\usepackage{lipsum} % for demonstration only

\section{How AMS article class works}

We can see the AMS Class is not expecting any data in the \bf first page footing \normalfont other than mandatory classification such as \bf 15-06 Proceedings, conferences, collections, etc. or optional thanks for grants \normalfont or other abstract key words\\\par Lots of good floating stuff \hfill \lipsum [1-2]

Answer 2

The easiest solution in this case seems to be adding the author symbols manually:

\documentclass[a4paper,11pt]{amsart}
\usepackage{amsmath,amssymb,amsthm, amsfonts,color}

\makeatletter
\newcommand\thankssymb[1]{\textsuperscript{\@fnsymbol{#1}}}
%\newcommand\thankssymb[1]{\lowercase{\textsuperscript{\@alph{#1}}}}
%\newcommand\thankssymb[1]{\textsuperscript{#1}}
\makeatother

\begin{document}

\title{A paper}

\author[F. Author]{First Author\thankssymb{1}}
\author[S. Author]{Second Author\thankssymb{2}}
\thanks{\thankssymb{1} for all the fish}
\thanks{\thankssymb{2} for all the chips}

\address{the department\\
a place}
\email[F. Author]{[email protected]} 
\email[S. Author]{[email protected]}

\begin{abstract}
the abstract
\end{abstract}

\maketitle

\section{intro}
lots of good stuff 

\end{document}

I defined a new command \thankssymb that takes a number as first argument, representing the author to be referenced and to be used in \author and \thanks.

Three example styles for \thankssymb are given for footnote symbols, lowercase letters and plain numbers, respectively. Note the use of lowercase inside the second variant, as the author names are typeset in uppercase letters in amsart.

Answer 3

Here is a "simpler" work around:

\author{First Author^1} \thanks{^1 Thanks\ for\ releasing\ fish}

The backslashes are need to keep the spaces in - dont know why.
