% Abstract of the paper
\begin{abstract}
This is a simple template for authors to write new IJMATH papers. The abstract should briefly describe the aims, methods, and main results of the paper. It should be a single paragraph not more than 300 words. No references should appear in the abstract.
\end{abstract}

%%%%%%%%%%%%%%%%% BODY OF PAPER %%%%%%%%%%%%%%%%%%
\section{Introduction}
This is a simple template for authors to write new IJMATH papers. See ijmath\_sample.tex for a more complex example, and ijmath\_guide.pdf for a full user guide.
All papers should start with an Introduction section, which sets the work in context, cites relevant earlier studies in the field by \cite{aut2018}, and describes the problem the authors aim to solve.
\section{Section}
Manuscripts should be divided into ordered and numbered sections. These sections should contain sufﬁcient details to allow others to replicate and build on published results. New methods and protocols should be described in detail while well-established methods can be brieﬂy described and appropriately cited. All headings (except Introduction and Conclusion) can be divided into subsections.
\subsection{Subsection}
\subsubsection{Sub-Subsection}
\inspace{2mm}%
Bulleted lists look like this:
\begin{itemize}
\item First bullet;
\item Second bullet;
\item Third bullet.
\end{itemize}
\noindent Numbered lists look like this:
\begin{enumerate}
\item First item
\item Second item
\item Third item
\end{enumerate}
\inspace{3mm}%
Mathematical definitions that can be used are as follows:
\begin{definition}
This is a definition
\end{definition}
\begin{remark}
This is a remark
\end{remark}
\begin{lemma}
This is a lemma
\end{lemma}
\begin{proposition}
This is a proposition
\end{proposition}
\begin{theorem}
This is a theorem
\end{theorem}
\begin{proof}
This is a proof
\end{proof}
\begin{proof}[Proof of Theorem 1.5]
This is a proof
\end{proof}
\begin{definition*}
This is a definition without number
\end{definition*}
\begin{proposition*}
This is a proposition without number
\end{proposition*}
\noindent Authors should provide a concise and precise description of the theoretical/experimental results, their interpretation as well as the conclusions that can be drawn in these sections.
\inspace{6mm}%
\textbit{Figures, Tables and Schemes}
\inspace{2mm}%
All ﬁgures and tables should be cited in the main text as Figure 1, Table 1, etc.
\begin{figure*}[h]
\begin{center}
\label{fig1}
\includegraphics[width=0.72\textwidth]{image1.png}
\caption{This is a ﬁgure. Schemes follow the same formatting. If there are multiple panels, they should be listed as: (a) Description of what is contained in the ﬁrst panel. (b) Description of what is contained in the second panel. Figures should be placed in the main text near to the ﬁrst time they are cited.}
\end{center}
\end{figure*}
\setlength{\tabcolsep}{5mm} % adjust space between the table columns
\renewcommand{\arraystretch}{1.0} % adjust space between the table rows
\begin{table}[h]
\label{table1}
\caption{This is a table caption. Tables should be placed in the main text near to the ﬁrst time they are cited}
\centering
\begin{tabular}{lll}
\hline
Title 1 & Title 2 & Title 3 \\
\hline
Data 1 & Data 3$^1$ & Data 5 \\
Data 2 & Data 4 & Data 6 \\
\hline
\multicolumn{3}{@{}l}{\footnotesize{$^1$Tables may have footer}}
\end{tabular}
\end{table}%
\inspace{2mm}%
\textbf{NOTE:} Tables, if preferred, can also be prepared in landscape format.
\inspace{6mm}%
\textbit{Mathematics}
\noindent Scalar variables are \textit{italic}; vectors are \textbit{bold italic} (no arrows); matrices are bold; dot products are denoted by a bold centred dot $\bullet$, cross-products by a bold multiplication sign $\times$. Differential d, complex i, exponential e, sin, cos, tan, log, etc., are not italic. Sub/superscripts that are physical variables are italic, while those that are merely labels are roman (e.g. $C_t$ and $F_v$ but $T_{\rm eff}$ and $b_{\rm max}$).
\inspace{7mm}%
\textbit{Equations}
\inspace{3mm}%
This is the example of a simple equation:
\begin{equation}
x=1
\end{equation}
\inspace{3mm}%
This is the example of a longer equation:
\begin{equation}
y=a+b+c+d+e+f+g+h+i+j+k+l+m+n+o+p
\end{equation}
\inspace{3mm}%
This is the example of a sequence of equations:
\begin{equation}
\begin{aligned}
x &= 1 \\
y &= 2 \\
z &= 3
\end{aligned}
\end{equation}
\section{Conclusion}
This last section should brieﬂy summarise what has been done, and describe the ﬁnal conclusions which the authors draw from their work.
