[Tex/LaTex] Insert ams classification in scrartcl

footnoteskoma-scriptmath-mode

How should I insert the AMS classification in the bottom of the first page ?

Google doesn't seem to say anything.

EDIT:
Here is the requested code:

\documentclass[12pt,numbers=withendperiod]{scrartcl} 

\newcommand\blfootnote[1]{%
  \begingroup
  \renewcommand\thefootnote{}\footnote{#1}%
  \addtocounter{footnote}{-1}%
  \endgroup
}

\begin{document}
\title{}
\author{}
\date{}
\maketitle

\section{Introduction}

\blfootnote{\textup{2000} \textit{Mathematics Subject Classification}: \textup{11D72}} 

\end{document}

Best Answer

The \subjclass command is defined in the ams class files, that is, it is defined in amsart.cls and amsbook.cls etc. In other words, it is not something you load from a package.

It essentially just sets a footnote. So you can follow this answer here to get a footnote without a marker, and just put in as the footnote text

\textup{2000} \textit{Mathematics Subject Classification}: \textup{<insert MSC here>}

Example:

\documentclass{scrartcl}

\makeatletter
\def\blfootnote{\gdef\@thefnmark{}\@footnotetext}
\makeatother

\begin{document}
\blfootnote{\textup{2000} \textit{Mathematics Subject Classification}:
code}
\end{document}

Which outputs on the bottom of the page:

Edit: It seems that the OP uses a different option for the presentation of the footnotes: I generally just use superscripts, but it appears that the OP may prefer numbers followed by a parenthesis. Here's a version that would allow that:

\documentclass{scrartcl}
\usepackage{etoolbox}

\newcommand\blfootnote[1]{%
  \begingroup
  \renewcommand\thefootnote{}\footnote{#1}%
  \addtocounter{footnote}{-1}%
  \endgroup
}
\deffootnote{0em}{1.6em}{\expandafter\ifdefempty\expandafter{\thefootnotemark}{}{\thefootnotemark)\enskip}}


\begin{document}
\blfootnote{\textup{2000} \textit{Mathematics Subject Classification}:
code}
\footnote{Normal footnote}
\end{document}

In this version etoolbox is used to conditionally set the parenthesis mark depending on whether \thefootnotemark is empty or not (the \expandafters are just kludged-together hacks since \ifdefempty doesn't expand all the way down, and it appears that \thefootnotemark expands to a macro which expands to a macro which expands to the empty string, so without the \expandafter the test fails). The output looks like this:
