Question

How to add author an affiliation and their email address and all left aligned?

title

author 1, author 2, author 3

Authors affiliation

author1 's email address

abstract

I'm using a single column article document. Title is in center of the page.

For a single application it's rather pointless defining an appropriate \maketitle command.

\documentclass[a4paper]{article}

\newcommand{\affilmark}[1]{\rlap{\textsuperscript{\itshape#1}}}
\usepackage{lipsum}

\begin{document}

\vspace*{3ex}
\begin{center}\LARGE
  The title of this paper, long enough to break over two lines
\end{center}
\vspace*{2ex}
\begin{flushleft}\large
A. N. Author\affilmark{a},\quad
B. P. Another\affilmark{b},\quad
C. Q. Third\affilmark{c}\\[2ex]
\normalsize\itshape
\textsuperscript{a,b}\,Department of Cuisine, University of Nowhere\\
\textsuperscript{c}\,Department of Departmentalization, University of Somewhere\\[1ex]
\upshape Corresponding author's email: \texttt{[email protected]}
\end{flushleft}
\vspace*{3ex}

\begin{abstract}
\lipsum[1-2]
\end{abstract}

\section{Introduction}
\lipsum
\end{document}

I would have also the title flush left.
