\section{Preparation of Manuscript\label{sec2}}
 The Title Page should contain the article title,
authors' names and complete affiliations, footnotes to the title,
and the postal address for manuscript correspondence (including
e-mail address). The Abstract should provide a brief
summary of the main findings of the paper.



\section{Introduction\label{sec1}}
 The Introduction should provide details of the application context and previous relevant publications, leading to a brief summary of the
direction of the research undertaken and the following structure of the article (Sections).

\subsection{Equations\label{subsec2.1}}

Equations should be typewritten by using \verb"equation, align, multline"
environments.
\begin{equation}\label{testequation1}
\text{This is a  sample equation:}\quad ax=c.
\end{equation}
Please \textbf{avoid the obsolete} \verb"\eqnarray" environment, which has several bugs.

\subsection{Numbered multi-line equations}

Numbered multi-line equations can be written in the following form:

\begin{example}\label{exm1}
\begin{align}
v_h(x_A,y_A)&=V_1(x_B,y_B),\label{eq1}\\
v_h^+(x_D,y_D)&=v_h^-(x_D,y_D).\label{eq2}
\end{align}
 \end{example}
\begin{example}\label{exm2}
\begin{equation}\label{eq3}
\begin{aligned}
u(t_{n+1})&=e^{\mathbf{L}h}u(t_{n})+e^{t_{n}\mathbf{L}}\int_{t_{n}}^{t_{n}+h}e^{-\tau \mathbf{L}}\mathbf{N}(\tau,u(\tau))\,d\tau,\\
v(t_{n+1})&=e^{\mathbf{L}h}u(t_{n})+\int_{0}^{h}e^{(h-\tau) \mathbf{L}}\mathbf{R}(t_{n}+\tau,u(t_{n}+\tau))\,d\tau.
\end{aligned}
\end{equation}
 \end{example}

\begin{example}\label{exm3}
\begin{align}
u(t_{n+1})&=e^{\mathbf{L}h}u(t_{n})+e^{t_{n}\mathbf{L}}\int_{t_{n}}^{t_{n}+h}e^{-\tau \mathbf{L}}\mathbf{N}(\tau,u(\tau))\,d\tau \nonumber\\
&\quad -e^{\mathbf{L}h}u(t_{n})+\int_{0}^{h}e^{(h-\tau) \mathbf{L}}\mathbf{R}(t_{n}+\tau,u(t_{n}+\tau))\,d\tau.\label{eq4}
\end{align}
 \end{example}

Equations should be cited by using the \verb"\eqref" command and the form \\ \verb"Eq.~\eqref{testequation1}" or simply\/ \verb"\eqref{testequation1}". In the text they appear as Eq.~\eqref{testequation1} or \eqref{testequation1}.

\subsection{Non-numbered equations}

For non-numbered equations, please use the commands
 \verb"equation*", \verb"align*", \verb"multline*" rather than
\verb"$$ $$" and  \verb"\[    \]".


\subsection{Theorems, corollaries, lemmas, definitions}
Definitions should be written by using the \verb"definition" command.

 \begin{definition}\label{def1}
A matrix $A$ is called invertible if there exists a matrix $B$ such that
$AB=BA=E$, where $E$ is the identity matrix.
 \end{definition}

On the other hand, theorems, corollaries and lemmas are typeset in italics.

\begin{lemma}\label{lem1}
If $A\geq 2-\epsilon$, then the Galerkin method is stable.
 \end{lemma}

Results from other sources can be written in the form
\begin{theorem}[cf.~Author \& Co-Author~\cite{firstauthor}]\label{thm1}
If $a\neq0$, then the Eq.~\eqref{testequation1} has a unique solution.
\end{theorem}
\begin{proof}
A special environment is predefined: the \textit{proof} environment. Please use

\verb"\begin{proof}"

proof of the statement

\verb"\qed"

\verb"\end{proof}"

for typesetting your proofs.
 \qed
\end{proof}

\subsection{References}

References should be listed at the end of the paper in alphabetical order according to the surnames of the first author, and should be cited in the text using \verb"\cite" command as \verb"\cite{coutsias1996,firstauthor,Berger,deBoor}". In the text the citations will appear as  \cite{coutsias1996,firstauthor,Berger,deBoor}.

 Abbreviations of titles of periodicals/books should be given by using Math. Reviews, see e.g. \verb"https://mathscinet.ams.org/msnhtml/serials.pdf"

\subsection{Figures}


Figures should be in a finished form suitable for publication   (preferably in eps format). Number figures consecutively with Arabic numerals.
Lettering on drawings should be  generated by high-resolution computer graphics and
large enough to withstand appropriate reduction for publication.
