\newtitle{How to Write an Abstract for the \\International Workshop on\\
          \medskip
          Optimization, Variational Analysis, and Control Theory}

\newabstract
This text is a style example for abstracts of the International Workshop on 
Optimization, Variational Analysis, and Control Theory (October 13-15, 2026, Hanoi, Vietnam), 
which must be written in \LaTeX-format, not to exceed one A4-page, and transmitted
electronically or sent as files in a diskette. You can load
the needed style file \verb|abs4ovact2026.sty| and this example file 
\verb|abs4ovact2026.tex| from our Web-page or ask us to send them to you.
It is recommended to copy this \LaTeX-file and modify it by your new content.

The title and the list of author's must be placed between the brackets 
\verb2{ }2 after the command \verb3\newtitle3 or \verb4\newauthor4, 
respectively. For long title and long list, use \verb5\\5 to demand line 
breaking followed by \verb6\medskip6 to have a suitable skip. The author
who will actually give the talk is marked by an underline (\verb7\underbar{ }7).
The upper index after every author's name made by a number in the brackets 
\verb2{ }2 after the command \verb7\no7 following the name is to indicate 
the corresponding address in the list at the end. To make this list, you have
 to use the command \verb8\newaddress{ }8 and the environment \verb9itemize9
with \verb0\no{ }0 in the bracket of \verb+\item[ ]+. For instance, the
list of addresses at the end of this text is written by
\begin{verbatim}
\newaddress{
  \begin{itemize}
    \item[\no{1,2}] Department of Optimization and Scientific Computing\\
      ...
      {\it lxthanh@math.ac.vn, nnthieu@math.ac.vn}
    \item[\no{3}] Interdisciplinary Center ... Heidelberg\\
      Im Neuenheimer Feld 368, 69120 Heidelberg, Germany\\
      {\it j.schloeder@iwr.uni-heidelberg.de}
  \end{itemize} }
\end{verbatim}
Please use \verb-{\it ...}- for e-mail address.

The proper content of abstract starts with the command \verb.\newabstract..
To begin a new paragraph just add a blank row in \LaTeX-file without any
skip command. Please do not include any figures in the abstract.

%  You can use the commands $\R$, $\N$, $\C$, and $\Q$ defined in abs4ovact.sty
%  for the sets of real or natural or complex or rational numbers.

\newaddress{
  \begin{itemize}
    \item[\no{1,2}] Department of Optimization and Scientific Computing\\
