# How can appear the authors and the interesting information when I use twocolumnfalse?

I want to write a springer article by using the \documentclass[twocolumn]{svjour3}. The problem is that when I use twocolumnfalse to write the abstract, the name of authors did not appear. This is my original code ( it is a springer template ):

\documentclass[twocolumn]{svjour3}
...
\begin{document}
%
\author{123 \and
456 \and
789
}
\institute{AAAAAA \at
BBBBB \\}
%
\twocolumn[
\begin{@twocolumnfalse}
\maketitle
\begin{abstract}
...
\end{abstract}
\end{@twocolumnfalse}
]


I tried that solution Here. but does not work.
