Copying title style

I want to know how to have the same title/author and section style as this (link)

I tried with book document class and

\chapter*{...}

[...]

\section{..}


but it's not the same thing.

It looks like a local formating. –  Sigur Nov 13 '13 at 0:02

Another solution... please try to be more specific...

\documentclass[11pt]{article}

\usepackage[latin]{babel} % demo only
\usepackage{lipsum} % demo only

\usepackage{setspace}

\begin{document}
{\noindent\bfseries\Huge\parbox{11cm}{\flushleft Old and New on the Schwarzian Derivative}}

\vskip14pt

\vskip24pt

\section{Introduction}

\noindent\lipsum[1-6]

\end{document}

-

This is almost what you want

\documentclass[12pt,a4paper]{article}

\begin{document}
\part*{Old and New on the Schwarzian Derivative}
