	\section{Introduction}
	

	
	The extended abstract should have at most 4 pages. Papers prepared more than 4 pages or out of the
	style of the meeting, will be returned.
	
	Here you should state the introduction, preliminaries and your notations. Authors are required to state clearly the
	contribution of the extended abstract and its significance in the introduction. There could be some short survey of
	relevant literature.
	
	\subsection{Instructions for speakers}
	
	While you are preparing your extended abstract, please take care of the following:
	
	{\bf Before submitting your extended abstract to the meeting, please rename its tex file by using the speaker's name
		(and a number, if the speaker is going to give more than one talk), e.g. if the speaker is D-Darvishi and he is going
		to give two talks, then the source file of the second talk should be named
		
		\centerline{D-Darvishi1.tex}
		
		You have to archive all source files in a .rar file and submit it through the conference website. Also you should
		submit the generated PDF. {\em Thus the submitted files must be like \lq\lq D-Darvishi1.rar and D-Darvishi1.pdf\rq\rq for the first talk and \lq\lq D-Darvishi2.rar and D-Darvishi2.pdf\rq\rq for the second talk.}}
	
	\begin{enumerate}
		\item Each participant can be a (co)author of at most 2 submitted papers.
		\item Extended abstract length: at least 2 pages and at most 4 pages.
		\item MSC2010: at least 1 item and at most 3
		\item Keywords: At least 2 items and at most 5 items.
		\item Authors: Full names, affiliations and emails of all authors. (Provide the emails at the end of the paper.)
		\item Margins: A long formula should be broken into two or more lines.
		\item Tags (Formula Numbers): Use $\backslash \text{\tt label\{A\}}$ and $\backslash \text{\tt eqref\{A\}}$. Remove
		unused tags.
		\item Acknowledgement: At the end of the extended abstract but before References, if there is any
		\item References: Use $\backslash \text{\tt cite\{X\}}$ to refer to the specific book or paper \cite{De}, whose
		bibitem code is $\backslash \text{\tt bibitem\{X\}}$ . Remove unused references. References should be listed in
		the alphabetical order according to the surnames of the first author at the end of the extended abstract and
		should be cited in the text as, e.g., \cite{Bu} etc. There should be no more than
		6 references.
		\item Abbreviations: Abbreviations of titles of periodicals or books should be given by using Math. Reviews. Find
		these abbreviations at \url{http://www.ams.org/mrlookup}.
		\item Everything before \verb+\begin{document}+ will be omitted in the compilation of \TeX files for the booklet ---
			except \verb+\usepackage+ commands. So do not add anything before \verb+\begin{documnet}+. Also most of the
				needed packages are previously included, so use other packages only if it is quite necessary.
				\item Do not define new commands and macros with \verb+\newcommand+ or \verb+\renewcommand+. If it is quite necessary
				and unavoidable, use only \verb+\def+ to define macros and place them after \verb+\begin{document}+.
					\item The English \TeX file can be compiled using PDF\LaTeX\ or XeLaTeX,  but not with \LaTeX.
					\item Pay attention to the comments in the \TeX\ files.

				 \section{Main results}\label{sec2}
				Please write the main results here.
				
				\subsection{Formulas}\label{subsec1}
				You are able to easily provide various types of the formulas by making use of the following instructions:
				
				\begin{enumerate}
					\item
					Formula within the text such as $AX+XB=C$.
					
					\item
					Formula in a separate line without number:
					\begin{equation*}
						\mathcal{K}_1(A,r_0)\subseteq \mathcal{K}_2(A,r_0)\subseteq \cdots \subseteq \mathcal{K}_d(A,r_0)=\cdots=\mathcal{K}_n(A,r_0).
					\end{equation*}
					
					\item
					Formula in a separate line with number:
					\begin{equation}\label{eq1}
						\mathcal{K}_1(A,r_0)\subseteq \mathcal{K}_2(A,r_0)\subseteq \cdots \subseteq \mathcal{K}_d(A,r_0)=\cdots=\mathcal{K}_n(A,r_0).
					\end{equation}
				\end{enumerate}
				
				The following is an example of definition.
				
				\begin{definition}
					Here, the body of the definition should be.
				\end{definition}
				%---------------------------------------------------------------------------------------%
				
				Here is an example of a table.
				
				\begin{table}[ht]
					\small
					\caption{Your table's caption}\label{eqtable}
					\begin{tabular}{ccc}
						\hline
						% after \\: \hline or \cline{col1-col2} \cline{col3-col4} ...
						col1 & col2 & col3 \\
						\hline
						4 & 5 & 6 \\
						7 & 8 & 9 \\
						\hline
					\end{tabular}
				\end{table}
				
				
				The following is an example of an example.
				
				%---------------------------------------------------------------------------------------%
				
				\begin{example}
					Let $D_{\infty}=<a,b|a^2=b^2=1>\cong {\mathbb Z}_2*{\mathbb Z}_2$ be the infinite dihedral group. Then
					$$M^{(2)}(D_{\infty})\not\cong M^{(2)}({\mathbb Z}_2)\oplus M^{(2)}({\mathbb Z}_2).$$
				\end{example}
				
				%---------------------------------------------------------------------------------------%
				
				The following is an example of a theorem and a proof. Please note how to refer to a formula.
				
				%---------------------------------------------------------------------------------------%
				
				\begin{theorem}\label{maintheorem}
					If ${\bf B}$ is an open ball of a real inner product space ${\mathcal X}$ of dimension greater than $1$, then there
					exist additive mappings $T: {\mathcal X}\to {\mathcal Y}$ and $b:{\mathbb R}_+\to {\mathcal Y}$ such that $f(x) = T(x)
					+ b\left (\|x\|^2\right )$ for all $x\in {\bf B}\setminus \{0\}$.
				\end{theorem}
				
				%---------------------------------------------------------------------------------------%
				
				\begin{proof}
					First note that if $f$ is a generalized Jensen mapping with parameters $t=s \geq r $, then
					
					\begin{align}\label{additive}
						f(\lambda(x+y))&=\lambda f(x) + \lambda f(y)\nonumber\\
						&\leq \lambda (f(x) + f(y))\nonumber\\
						&= f(x) + f(y)
					\end{align}
					
					for some $\lambda \geq 1$ and all $x, y\in {\bf B}\setminus \{0\}$ such that $x \perp y$.
					
					\medskip
					\noindent \underline{\rm Step (I)- the case that f is odd:} Let $x \in {\bf B} \setminus \{0\}$. There exists $y_0 \in
					{\bf B} \setminus \{0\}$ such that $x \perp y_0$, $x + y_0 \perp x - y_0$. We have
					\begin{eqnarray*}
						f(x)&=& f(x)- \lambda\, f\left ( \frac{x+y_0}{2\, \lambda}\, \right
						) -
						\lambda \, f\left ( \frac{x-y_0}{2\, \lambda}\, \right )\\
						&&+ \, \lambda \, f\left ( \frac{x+y_0}{2\, \lambda}\, \right ) -
						\lambda^2\, f\left ( \frac{x}{2\, \lambda^2}\, \right ) - \lambda^2
						\, f\left (
						\frac{y_0}{2\, \lambda^2}\, \right )\\
						&=& 2\, \lambda^2 \, f\left ( \frac{x}{2\, \lambda^2}\, \right ).
					\end{eqnarray*}
					
					\medskip
					\noindent \underline{\rm Step (II)- the case that f is even:} Using the same notation and the same reasoning as in the
					proof of Theorem \ref{maintheorem}, one can show that $f(x)=f(y_0)$ and the mapping $Q: {\mathcal X}\to {\mathcal Y}$
					defined by $Q(x) : = (4\lambda^2)^n f((2\lambda^2)^{-n}x)$ is even orthogonally additive.
					
					\medskip
					Now the result can be deduced from Steps (I) and (II) and Formula \eqref{additive}.
				\end{proof}
				
				\begin{proposition}
					This is a proposition.
				\end{proposition}
				
				\begin{corollary}
					This is a corollary.
				\end{corollary}
				
				\begin{question}
					Is this a question?
				\end{question}
				
				\begin{solution}
					Yes.
				\end{solution}
				
				\begin{remark}
					This is a remark.
				\end{remark}

				An important note is described here.

				\section{Numerical results}\label{sec3}
				Numerical results section, if included, appears here.
				
				\subsection{Table and Figure}\label{subsec3}
				By making use of the \texttt{table} and \texttt{figure} environments, you are able to create a table or figure in the paper. In view of the fact that tables and figures are float environments, it is possible that they do not place exactly where you have mentioned them in the source. You can also refer to them, like Table \ref{tab1} and Figure \ref{fig1}.
