one and two column on the same page

[Dominique Roddier]

Is it possible to toggle \onecolumn and \twocolumn on the same page
without having latex perform the \clearpage command.
Basically, I need my abstract to be across the whole page (onecolumn)
but then the paper underneath is in two column format and I can't
get it to start on the same page.

Thanks
Dominique.

No... but you don't need that.

As you have seen, \maketitle already does this with the title.

You can define a document class to put the abstract in as part
of the title by redefining \maketitle.

Or you can call \twocolumn explicitly. This requires some tricks:
\begin{document}

\twocolumn[
\begin{@twocolumnfalse}

\maketitle
\begin{abstract}
...
\end{abstract}

\end{@twocolumnfalse}
]

Unfortunately, \thanks will not work in the author list. If you need such
specially-numbered footnotes, you can make them like this:

\title{Demonstration}
\author{Me, You\thanks{}}% No point in typing anything here!
\begin{document}

\twocolumn[
... as above ...
]
{\renewcommand\thefootnote{\fnsymbol{footnote}}
\footnotetext[1]{Thanks for nothing!}
}

Get multicol.sty (or rather multicol.{ins,dtx}). And say
\begin{multicols}{2}
...
\end{multicols}

Maybe this is a newbie suggestion, but you could use \mark and then a
conditional in your headline, so that if the mark is on the page that is
currently being processed for output, it will get a headline that sneakily
includes the abstract.
