%\section{\bf Math environments, Figures, Tables and References }
\section{\bf Main Results }
\subsection{\bf Definitions and Remarks}
For definitions and remarks please use the
standard commands \verb+\+begin\{\dots\} and \verb+\+end\{\dots\}.
However all texts in such a environment should be automatically
\textbf{normal}.
\begin{definition}
	This is a definition
\end{definition}

\begin{remark}\label{rem:myrem}
	This is a remark
\end{remark}


\subsection{\bf Theorems, lemmas, propositions, corollaries}
To produce a theorem, lemma, proposition and corollary
etc., you need to use the standard command \verb+\+begin\{\dots\} to
start with, and \verb+\+end\{\dots\} to finish.  All texts in such
environment should be automatically \textbf{\emph{italic}}. 
For all proofs, please use \verb+\+begin\{proof\} and
\verb+\+end\{proof\} commands. Do not define your own macros.
A Sample theorem and its proof may be written as follows

\begin{theorem} \label{thm:compactclose} % of course, label is optional
	Each compact subset of a Hausdorff space is closed.
\end{theorem}
\begin{proof}
	Let $A$ be a compact subset of the Hausdorff space $X$. To show that $A$ is
	closed, we will show that its complement is open ... .
\end{proof}

\begin{lemma}\label{lem:myfirstlemma}
	This is a lemma.
\end{lemma}
\begin{proof}
	This is the proof of the above lemma.
\end{proof}
\begin{proposition}\label{pro:myfirstprop}
	This is a proposition.
\end{proposition}
\begin{proof}
	This is the proof of the above proposition.
\end{proof}

 
\begin{corollary}\label{cor:mycor}
	This is a corollary.
\end{corollary}
\begin{proof}
	This is the proof of the above corollary.
\end{proof}


For equations that you wish to be automatically
numbered sequentially throughout the text, use the \texttt{equation}
environment, e.g.
\begin{equation}
b(u^n, v - u^n) \geq
\left(u^{n-1}, v - u^n \right), \quad \forall v \in \mathcal{K}^n.
\end{equation}

%%%
%%% Section 4
%%%
LaTeX is automatically labeling the equations. To to omit numbering simply use 
(\verb"\[") and close (\verb"\]") e.g.
\[b(u^n, v - u^n) \geq
\left(u^{n-1}, v - u^n \right), \quad \forall v \in \mathcal{K}^n.\]
 

Part numbers for sets of equations may be generated using the
\texttt{subequations} environment, e.g.,
\begin{subequations}\label{eps2}
	\begin{align}
	&\frac{\partial \bar{\epsilon}}{\partial t} - \frac{\partial^2 \bar{\epsilon}}{\partial x^2} = 0, \quad
	\hbox{in}  \quad \bar{\Omega},  \label{eps2:a} \\
	&\bar{\epsilon}(x,0) = 0,  \quad\quad  a < x < +\infty, \label{eps2:b} \\
	&\bar{\epsilon}(a,t) = \epsilon(a,t),  \quad 0< t <  t_{max}, \label{eps2:c} \\
	&\bar{\epsilon} \longrightarrow 0, \quad  \hbox{when}  \quad x \longrightarrow +\infty. \label{eps2:d}
	\end{align}
\end{subequations}
 In the following, we number several equations in an align environment using only one number:
 \begin{equation}
 \begin{aligned}
 \boldsymbol{\alpha}^\top \mathbf{B} \boldsymbol{\alpha}
 & = \sum_{i=1}^m \sum_{j=1}^m \alpha_i \mathbf{B}_{ij} \alpha_j \\
 & = \sum_{i=1}^m \sum_{j=1}^m \alpha_i \alpha_j \int_{-1}^1 \varphi'_i(x) \varphi'_j(x) dx \\
 & = \int_{-1}^1 \left(\sum_{i=1}^m \alpha_i  \varphi_i'(x) \sum_{j=1}^m  \alpha_j  \varphi_j'(x) \right) dx \\
 & = \int_{-1}^1  \left(\alpha_h'(x)\right)^2  dx \geq 0.
 \end{aligned}
 \end{equation}
   
 \subsection{\bf Figures}
To insert one-column wide figures use
 \begin{verbatim}
 \begin{figure}[ht]
\includegraphics[width=8cm]{logo.eps}
\caption{A simple figure: MACO official logo.}
\label{fig:logo}     
\end{figure}
 \end{verbatim}
 \begin{figure}[ht]
 	\includegraphics[width=8cm]{logo.eps}
 	\caption{A simple figure: MACO official logo.}
 	\label{fig:logo}     
 \end{figure}
 The .eps file must be included in the same directory as the .tex file.
\subsection{\bf Tables} 
 Tables are created using the “table” environment given below:
\begin{verbatim} 
\begin{table}[where]
	table
\end{table}
\end{verbatim} 
The argument “where” above specifies the allowed locations for the
table. An example of table with three columns is given below. The resulting table is illustrated on table \ref{table:errors}.
\begin{verbatim} 
\begin{table}[h!]
\centering
\begin{tabular}{cccc}
\hline
\hline
$S$ &\bf{Exact Values}&\bf{Estimate Values} \\
\cmidrule(l){1-1}\cmidrule(l){2-2}\cmidrule(l){3-3} 
{80}  & $ 21.6059$ & $ 21.6072 $& \\
{85}  & $ 18.0374$ & $ 18.0397 $&   \\
{90}  & $14.9187$  & $ 14.9187 $&   \\
{95}  & $12.2314$  & $ 12.2306 $&   \\
{100} & $ 9.9458$  & $ 9.9450  $&   \\
{105} & $ 8.0281$  & $ 8.0270  $&   \\
{110} & $ 6.4352$  & $ 6.4349  $&   \\
{115} & $ 5.1265$  & $ 5.1266  $&   \\
{120} & $ 4.0611$  & $ 4.0639  $&   \\
\hline
\hline
\end{tabular}  
\caption{A simple table.}
\label{table:errors}
\end{table}
\end{verbatim}  
 
 \begin{table}[h!]
 	\centering
 	\begin{tabular}{cccc}

\subsection{\bf References}\label{refs}

%\subsection{Including References in the Text} %%%%%%%%%%%%%%
\label{S-references}
The usual way to input references in the text is with the 
\verb+\cite{label-ref}+ command where \verb+label-ref+ is a label
unique for each reference.  References cited in the text should be
defined in the environment \verb+{thebibliography}{}+.
In this journal, we use the \textbf{plian} bibliography style. 
In the plain style, references listed in alphabetical order and labeled numerically.
The unused references must be removed.
Each bibliographical entry has a key, which is assigned by the author and used to refer to that entry in the text. For instance, the right style for references  \cite{achdu} \cite{Stampacchia}, \cite{toivanenkou} and \cite{knuth} is given here:

\begin{Verbatim}[breaklines=true, breakanywhere=true]

\bibitem{achdu}
Y. Achdou and O. Pironneau,
\newblock {\em Computational methods for option pricing}, 
volume~30 of {\em Frontiers in Applied Mathematics}.
\newblock Society for Industrial and Applied Mathematics (SIAM), Philadelphia,
PA, 2005.

\bibitem{Stampacchia}
P. Hartman and G. Stampacchia,
\newblock On some non-linear elliptic differential-functional equations.
\newblock {\em Acta Mathematica}, {\bf 115}(1):271--310, 1966.


\bibitem{toivanenkou}
J. Toivanen,
\newblock Numerical valuation of European and American options under Kou's
jump-diffusion model.
\newblock {\em SIAM Journal on Scientific Computing}, {\bf 30}(4):1949--1970, 2008.

\bibitem{knuth}
D.E. Knuth,
\newblock {\em The \TeX Book},
\newblock Addison Wesley Professional, 21st edition, Boston, 1986.



\end{Verbatim}

Another way to input references in the article is to use the BibTex tool. 
Each reference in this case should be written and stored in a separate BibTeX database (.bib file). 
Then the .bib file is recalled in the main source file of the article using following commands:
\begin{verbatim}
\bibliographystyle{plain}
\bibliography{your_bib_file_full_directory}
\end{verbatim}
By running the BibTex  bibliography processor, citations and reference list are automatically formatted consistently in the \textbf{plain} style.

%%%
%%% Conclusion
%%%

\section*{\bf Conclusion}
The unnumbered section conclusion must be included as the last part of the paper.
The conclusion usually contains a brief summary of the article.
%%%
%%% Acknowledgments
%%%
\section*{\bf Acknowledgments}
The unnumbered section acknowledgments is usually placed before the references to thank all those who have helped in carrying out the research.



%%%
%%% Appendices
%%%
\appendix
\section{\bf Appendices}
Appendices should be set after the references, beginning with the
command \verb"\appendix" followed by the command \verb"\section"
for each appendix title, e.g.
%
\begin{verbatim}
\appendix
\section{\bf This is the title of the first appendix}
\section{\bf This is the title of the second appendix}
\end{verbatim}

Subsections, equations, theorems, figures, tables, etc. within
appendices will then be automatically numbered as appropriate.
