如何在标题等中获取作者姓名？

Question

authblk将作者存储在两个宏\AB@authlist和中\AB@authors。第一个具有以下结构：

\protect\@nameuse{@sep1} \protect\Authfont AUTHORNAME\protect\footnote {AFFILL}\protect\textsuperscript {,}
\protect\@nameuse{@sep2} \protect\Authfont AUTHORNAME\protect\footnote {AFFILL}\protect\textsuperscript {,}
…

第二个就复杂多了。这个包用 counter 来统计作者的数量authors。

如果计数器authors小于 3，我们可以简单地使用它\AB@authlist来显示页眉中的作者。但是如果它大于或等于 3，我们必须拆分第一作者。这可以通过一个简单的分隔参数来完成：

\documentclass[a4paper,10pt]{article}
\usepackage{amsmath,amsfonts,amsthm,dsfont,amssymb,lipsum}
\usepackage[blocks]{authblk}
\newenvironment{keywords}{\noindent\textbf{Keywords:}}{}
\newenvironment{classification}{\noindent\textbf{AMS subject classifications.}}{}

\newcommand{\email}[1]{\texttt{\small #1}}

\makeatletter
\newcommand*{\authors}{%
  \begingroup
    \let\footnote\@gobble% ignore \footnote
    \let\textsuperscript\@gobble% ignore protected \textsuperscript
    \expandafter\let\csname textsuperscript \endcsname\@gobble
    \let\Authfont\relax% do not use a special font
    \def\Authand{, }% separate list of authors by ,
    \ifnum\value{authors}<3 % one ore two authors
      \AB@authlist% show them all
    \else% 3 or more authors
      % show only the first one followed by "et.~al"
      \expandafter\@firstof@authlist\AB@authlist\@nil\ et.~al%
    \fi
  \endgroup
}
\def\@firstof@authlist#1\footnote#2\@nil{#1}% skip all from the first footnote
\makeatother

\usepackage{fancyhdr}

\pagestyle{fancy}
\fancyhf{}
\fancyhead[C]{%
  \ifodd\value{page}
    \small\nouppercase\authors
  \else
    \small\nouppercase\shorttitle
  \fi
}
