These instructions describe how to prepare and submit an article using \LaTeX{} and \texttt{cmpj3.sty} for publishing in ``Condensed Matter Physics'' journal. Each submitted manuscript must contain an abstract reflecting the essence of the study. The abstract will be published separately from the article in a variety of bibliographical services so it should be completely self-contained (\emph{no footnotes or numbered references}). Extremely important references may be incorporated into the abstract itself: [Thor~A.~U., et al., Condens. Matter Phys., 2004, \textbf{7}, 111]. The abstract must be written as a single paragraph not exceeding 150 words. Mathematical expressions are discouraged. Please define all nonstandard symbols and abbreviations.

\section{Editorial process: from submission to offprints}

This guide is intended to help in preparing \LaTeX{} manuscripts for publication in ``Condensed Matter Physics'' (hereinafter CMP) journal. We appreciate your effort to follow our style in preparing your article for mutual benefit: speedier publication, greater accuracy and higher quality. Below is a description of the features of CMP style. In addition, you will find some general advice and specific remarks on preparing your manuscripts.

Authors are encouraged to submit their manuscripts electronically through the CMP journal management and publishing system at 
\begin{center}
	\texttt{\url{https://cmpj2.icmp.lviv.ua/index.php/cmpj/about/submissions}}.
\end{center}
Third-party submissions cause excessive problems. Author self-submissions are exceedingly preferred. All appropriate files (\LaTeX{} sources and figure files) should be combined into a single \href{https://en.wikipedia.org/wiki/Archive_file}{\textbf{archive file}}. All information about the submission must be included in the submission form. This must include: full names, affiliations, postal and e-mail addresses, and \href{https://orcid.org/}{ORCID ID's} of all authors, the full title of the article, and the full list of files in the attached archive.

Please check your article carefully for accuracy, consistency and clarity before submission. Ask someone else (preferably native speaker or person with perfect knowledge of English) to read the manuscript, however satisfied you may be with its quality. Your colleague can often find errors or obscure passages missed by the author.

Manuscripts must be coded in \LaTeXe{} with the \verb|article| class, preferably using the CMP journal style, which must be included in your \TeX{} distribution, and is also available at the journal Web page
\begin{center}
	\texttt{\url{https://cmpj2.icmp.lviv.ua/index.php/cmpj/about/submissions}}
\end{center}
or from the Comprehensive \TeX\ Archive Network (CTAN)
\begin{center}
	\texttt{\url{http://www.ctan.org/pkg/cmpj}}
\end{center}

In order to avoid problems with the non-Latin letters and symbols, we strongly encourage using of the UTF-8 text encoding
\begin{center}
	\verb|\usepackage[utf8]{inputenc}|
\end{center}
although the Cyrillic Windows-1251 (CP1251) encoding is also acceptable
\begin{center}
	\verb|\usepackage[cp1251]{inputenc}|
\end{center}

For old \TeX{} distributions, as well as, in the case of problems with missed packages, it is recommended to use the ``\texttt{cm}'' option, e.g.,
\begin{center}
	\verb|\usepackage[eqsecnum,cm]{cmpj3}|
\end{center}

Manuscript should be arranged in the following order: title of article, short title of not more than 45~characters, author's name and affiliation, abstract (up to 150~words), up to six keywords and optional PACS numbers, text of the article, acknowledgements, appendices and references. At the end of the document or in separate file, the contributors are asked to provide title, authors names and affiliations, abstract and keywords in Ukrainian (see subsection \ref{ua-part}). Figures and tables must be included in the text where they have appeared or at the end of the article.

The Editorial Office acknowledges receipt of a manuscript by e-mail to the corresponding author. All contributions will be evaluated according to the standard procedures of peer review, usually by two referees. Only contributions which meet the scientific and formal standards of the journal can be accepted for publication. The Editorial Office will send an acceptance letter to the corresponding author. Proofs are provided in the form of PDF files after preparing an article for publishing by the production department. Authors should prepare a list of necessary corrections as soon as possible and upload it at your submission dashboard or e-mail it to the Editorial Office. All articles are freely available in electronic forms (PDF) at the journal Web page:
\begin{center}
	\texttt{\url{https://cmpj2.icmp.lviv.ua/index.php/cmpj/index}}
\end{center}

We look forward to receiving your articles!




\section{Style guide}


\subsection{Title information}

The manuscript must begin with the title of the paper in lower case letters except for proper nouns, certain abbreviations, physical quantities, chemical symbols etc. The use of nonstandard abbreviations and acronyms is not allowed. Unnecessary words in the title must be dropped. The title is followed by the names of all authors (with first name initials) and the corresponding institutions (from the smallest to the largest unit, e.g. group, department, university) with addresses, as given in the above example (street or P.O. box, city with postcodes, country). Countries must be written in English. There are two slightly different forms of affiliations in the CMP style depending on whether all authors work in the same institution. The corresponding author electronic mail address can be placed in a footnote.

It is strongly encouraged to provide ORCID (\url{https://orcid.org/}) for all authors. ORCID for primary and/or corresponding author is mandatory.

An abstract must accompany each manuscript; it should be completely self-contained, not exceeding 150 words and written as a single paragraph. Mathematical expressions must be avoided.

Up to six keywords (Physics Subject Headings) 
\begin{center}
	\texttt{\url{https://physh.aps.org/browse}}
\end{center}
must at a glance give a general idea of the article to a reader.

\href{https://en.wikipedia.org/wiki/Physics_and_Astronomy_Classification_Scheme}{PACS} numbers (up to six classification codes) are optional and used to select an appropriate journal section. The principal number must be placed first.


\subsection{Main body of the paper}

The CMP style makes use of the conventional \LaTeX{} document layout so below we will only point out peculiarities of the style and some important general features (see also section~\ref{tex-issues} for \TeX{}-related issues).

The body of the paper must be divided into sections, subsections etc. (however, in short papers section may not be necessary) using standard \LaTeX{} commands. Text must be typed as usual. Compounded words like ``semi-infinite, $a$-axis'' are separated by a short hyphen ``\verb|-|'', the en-dash ``\verb|--|'' is used in number ranges (20--25\textcelsius, 4--5~\textmu{}m) and em-dash ``\verb|---|''~--- in sentences. Please, make a difference between left and right quotes (\verb|`| vs. \verb|'| or \verb|``| vs. \verb|''|, respectively) instead of using the symbol \verb|"| everywhere. \emph{Emphasized text} is obtained with the command \verb|\emph{...}|. Extra or exceptional hyphenations are added by means of the command \verb|\hyphenation|, which must be placed in the preamble of the document.

Use \verb|\label| and \verb|\ref| for cross-references to equations, figures, tables, sections, subsections, etc., instead of plain numbers. The \verb|\label| instruction must be typed immediately after (or one line below), but not inside the argument of a number-generating instruction such as \verb|\section| or \verb|\caption|, roughly in the position where the number appears, in environments such as \texttt{equation}, \texttt{figure}, \texttt{table}, etc.

A limited number of user-defined macros can be placed in the preamble of the article, and not at any other place in the document. Such user-defined macros, i.e. the one made using the commands \verb|\newcommand| and \verb|\newenvironment|, should be used with great care. Large macro packages should be avoided. User-defined macros that are not used in the article must be omitted. Do not change existing environments, commands and other standard macros of \LaTeX{}. A short description of the user-defined macros, in the form of \TeX{} comments, is appreciated. Deviation from these rules may cause inaccuracies in the article or a delay in publication.

Footnotes must be avoided whenever possible. If required they can be used only for brief notes that do not fit conveniently into the text. The standard \LaTeX{} macro \verb|\footnote| must be used and will normally give an appropriate symbol.

Your article will be read by many people whose native language is not English, so keep sentences as short and simple as possible. UK~English spellings are preferred (colour, flavour, behaviour, tunnelling, artefact, focused, focusing, fibre, etc.). Using of ``-ize'' spellings is encouraged (diagonalize, renormalization, minimization, etc.). The words ``table'', ``figure'', ``equation'' and ``reference'' must be written in full and \emph{not} contracted to ``Tab.'', ``Fig.'', ``eq.'' and ``Ref.''




\subsection{Mathematical material}

\subsubsection{General advice}

For in-line formulas use \verb|\(...\)| or \verb|$...$|: $E_{\textrm{F}}$, \(T_{\textrm{C}}=123\)~K. Avoid built-up constructions, for example fractions, matrices, integrals, sums, etc., in in-line formulas. For unnumbered displayed one-line equations use the \verb|displaymath| environment or the shorthand notation \verb|\[...\]|. For numbered displayed one-line formulas use the \verb|equation| environment. Do \emph{not} use \verb|$$...$$|, but only the \LaTeX{} environments, so that the document style determines the formula layout. For example, the definition of Dirac $\delta$-function in the Fourier representation looks like
\begin{equation}
\label{delta-def}
\delta(x) = \frac{1}{2\piup}
           \int_{-\infty}^{\infty} \re^{\ri sx}
           \rd s,
\end{equation}
where the expression $\re^{\ri sx}$ is tolerable, but the exponents with more complex arguments should be replaced by $\exp({\ri sx})$. For displayed multi-line formulas use the standard \verb|eqnarray| environment or \verb|align| one of the \AmS-\LaTeX{} bundle. For example,
\begin{align}
\Delta^{(+)} &\equiv 1-\Theta \left[\varphi^{(+)}_1 Q_{11}+\varphi^{(+)}_4 Q_{22}\right]
-\Theta \left[\varphi^{(+)}_2 +\varphi^{(+)}_3\right] Q_{12}
\nonumber\\
&+\Theta^2 \left(Q_{11}Q_{22}-Q_{12}^2\right)\left[\varphi^{(+)}_1 \varphi^{(+)}_4 -
\varphi^{(+)}_2 \varphi^{(+)}_3\right]=0. 
\label{multi-line}
\end{align}
Please note that the equation number is placed in the last line of the multi-line mathematical expression numbered as a whole.

Keep in mind that an \emph{empty} line in \TeX{} sources starts a \emph{new} paragraph! So do \emph{not} separate mathematical environments (and other too!) by empty lines unless you do \emph{want} to start a paragraph at this place!





\subsubsection{Roman vs. italic}


In mathematics mode \LaTeX{} automatically sets variables in a math italic font. Such an italicization is accepted in general. However, there are some cases where it is better to use an upright font to mark a special meaning of certain symbols: the Euler number ``$\re$'', mathematical constant ``$\piup$'', ``$\ri$'' when used as imaginary unit ($\ri=\sqrt{-1}$), differential ``$\rd$'', and the operators ``$\Im$'' and ``$\Re$'' for the imaginary and real parts of complex numbers, respectively [see equation~(\ref{delta-def}) for example] and \verb|cmpj3.sty| provides commands \verb|\re|, \verb|\piup|, \verb|\ri|, \verb|\rd|, \verb|\Im|, and \verb|\Re| for typesetting such symbols, respectively.

Mathematical functions, such as \verb|cos|, \verb|sin|, etc., must appear in Roman type. \LaTeX{} provides built-in commands for most of these functions (e.g.\ \verb|\cos| and \verb|\sin|, respectively).

Subscripts and superscripts must be in Roman type if they are labels rather than variables or characters that take values: $k_{\textrm{B}}$ (Boltzmann constant), $E_{\textrm{F}}$ (Fermi energy), $T_{\textrm{C}}$ (Curie temperature) and $c_{\textrm{ion}}$ (ion concentration), but $A_{pq}=\langle p |\hat A| q\rangle$ for matrix elements.

Units (e.g. V/cm or V~cm$^{-1}$, K, Pa, \textmu{}m, etc.) must be written in text mode (not in math environment) with a nonbreakable space to the number before: $T_{\textrm{C}}=123$~K, but $t_{\textrm{C}}=-150$\textcelsius. Symbols of chemical elements are also typed in text mode: H$_2$O, Ca$^{2+}$, $^{14}$N$_2$, etc.


\subsection{A few miscellaneous remarks}

Mathematical expressions are rather sophisticated object to type out. Below there is a list of the most simple and common errors which one should avoid.
\begin{itemize}
%
\item
%
For simple fractions in text the slash \verb|/|, as in $\hbar=h/2\piup$, must be used instead of \verb|\frac| or \verb|\over|, care being taken to use parentheses where necessary to avoid ambiguity, for example to distinguish between $1/(n-1)$ and $1/n-1$. Exceptions to this are the proper fractions $\frac12$, $\frac13$, $\frac34$, etc., which are better left in this form. In displayed equations horizontal lines are preferable to solidi provided the equation is kept within a height of two lines. A two-line slash should be avoided where possible; the construction $(\ldots)^{-1}$ must be used instead.
%
\item
%
Angle brackets (e.g. the ``bra-ket'' notation, average values and Green functions) are obtained with \verb|\langle| and \verb|\rangle| commands: $\langle p|q \rangle$, $\langle S^z \rangle$ and $\langle\langle a_i | a^{\dag}_j \rangle\rangle_{\omega}$.
%
\item
%
The symbol \verb|\mid| must be used as binary operator only. The character ``~$|$~'' is a proper element of such mathematical constructions as modulus, the ``bra-ket'' notation and Green functions: $X^{pq}= |p\rangle \langle q|$ and $A=|b/c|$.
%
\item
%
The root sign $\sqrt[n]{x}$ looks fine with simple expressions only, the power $1/n$ must be used for complex ones.
%
\item
%
Braces, brackets and parentheses should be used in the following order: $\{[(\;)]\}$. The same ordering of brackets must be used within each size. However, this ordering can be ignored if the brackets have a special meaning.
%
\item
%
Decimal point (not comma!) must be used in decimal fractions.
%
\item
%
Do not use obsolete commands \verb|\rm|, \verb|\bf|, \verb|\sf|, etc., for font switching, use \verb|\textrm|, \verb|\textbf|, \verb|\textsf|, etc., instead.
%
\item
%
Please treat mathematics as a part of text, writing down punctuation marks where necessary.
\end{itemize}


\subsection{Floats: figures and tables}


Put the tables and figures in text with the \verb|table| and \verb|figure| environments, and position them near the first reference of the table or the figure. Each table or figure must have an explanatory caption which should be as concise as possible. If a table or figure is divided into parts these must be labelled (a), (b), (c), etc., but there must be only one caption for the whole float, not separate ones for each part. The caption comes \emph{before} the table and \emph{after} the figure with a full stop at the end. Simple samples are presented here (see figure~\ref{fig-smp1} and table~\ref{tbl-smp1}).

\begin{figure}[htb]
\centerline{\includegraphics[width=0.65\textwidth]{eps_demo}}
\caption{This is a sample of true EPS figure which allows arbitrary scaling without the loss of quality. Figure must be centred in the line.} \label{fig-smp1}
\end{figure}

\end{tabular}
\renewcommand{\arraystretch}{1}
\end{center}
\end{table}

Where possible tables should not be broken over pages. If a table has related notes these must appear directly below the table rather than at the bottom of the page. Notes can be designated with footnote symbols. The \verb|minipage| environment is useful in this case.

Figures can be included in an article as PDF, JPEG, or PNG files by means of the \verb|\includegraphics| command or using the \LaTeX{} picture environment. Encapsulated PostScript (EPS) files are also valid. Each figure must have a brief caption describing it and, if necessary, interpreting the various lines and symbols on the figure. As much lettering as possible should be removed from the figure itself and included in the caption.

Keep in mind that your tables and figures may move from their original places during preparation of the article for publishing. Collecting all tables and figures at the end of the article is acceptable but undesirable.


\subsection{How to prepare a good figure}

\emph{Authors must keep in mind that the final printed quality of illustrations can never be better than the one of original artwork.}

Figures must be carefully prepared and submitted ready for reproduction. Figures are often reduced to half of their original size so lettering and symbols must be clear and large enough (smallest letters must not be smaller than 2~mm, line width should be greater than 1~pt). All figure elements must be of proportional sizes and have uniform width and contrast. Avoid small open symbols, small dots, small decimal points, hairlines, close-dotted or short-dashed lines. Draw a closed axes frame in diagrams with the axis titles (quantity followed by the unit in brackets) parallel to the corresponding axis, outside the frame. For numbers, use a decimal point instead of a comma. Authors must avoid including any unnecessary text around a figure, such as captions, figure numbers, author or file names. Grey scales in plots and diagrams, which might get difficult to distinguish after reducing, or which often disappear during the printing process, should be avoided. Labelling must be uniform throughout all figures. Lettering should not be pasted on to the figures as it may easily become detached as a result of handling.


Colour figures submitted in electronic format will generally remain in colour in the electronic versions of an article at no cost. However, in the paper version of the CMP journal figures are printed in black and white or grayscale.

Roughly speaking, there are two types of electronic figures: vector graphics and bitmap graphics. A \emph{vector} image is a set of arranged objects: lines, polygons, ellipses, shades, characters, etc. Such an image allows almost arbitrary scaling without loss of quality. Vector images are typically charts, plots, diagrams, etc., produced by various computer software. A \emph{bitmap} image is a two-dimensional array of pixels (PICture'S ELements) or ``dots''. Continuous tone photographs are the most common samples (like figure~\ref{fig-smp2}). Image quality is determined by DPI (Dot Per Inch --- a pretty self-explained definition). Below, there are necessary requirements for each type of images.

\end{figure}
%
\begin{description}
%
\item[Vector images] are to be prepared in Portable Document Format (PDF) or Encapsulated PostScript (EPS) format. The Bounding Box must indicate the area of the figure with a minimum of white space around it and not the dimensions of the page. Please make sure to use only standard fonts (Helvetica or Arial, Times or Times New Roman, Symbol) or embed the required fonts in the image file. Authors must avoid using special effects generated by including verbatim PostScript code within the \LaTeX{} file with specials other than the standard figure inclusion one. 
%Files must be prepared in ASCII format (not binary) with no TIFF preview. If Windows Postscript drivers are used, check that the Postscript option is set to Encapsulated Postscript (EPS).
%
\item[Bitmap images] must be sent in PNG, JPEG, or TIFF formats. Continuous-tone figures must have at least 300~DPI, line drawings -- 600~DPI minimum resolution in final size. Screen or web resolution is \emph{absolutely insufficient} for publication. If authors convert the bitmap image to PDF or EPS formats and include it in such a form in the manuscript, they must also send an original bitmap version of the image to the Editorial Office.

%Use of lossy JPEG (JPG) format (or JPEG compression) is \emph{strictly prohibited} for images with sharp margins (especially line-art) because of large visible artefacts. 
Continuous-tone images (especially large figures with good resolution) in JPEG format must be created with \textit{compression} set to ``High quality''.
\end{description}

Every time if you are in doubt, please feel free consult the Editorial Office and you will receive an advice of our \TeX{}nical Editor.

The acknowledgement section follows the main body of the paper and precedes any appendixes. This unnumbered section starts with command
\\
\strut\hfill%
\verb|\section*{Acknowledgments}|%
\hfill\strut%
\\
Technical detail that it is necessary to include, but that interrupts the flow of the article, may be consigned to an appendix. Any appendixes must be included at the end of the main text of the paper, after the acknowledgements section (if any) but before the reference list. The command \verb|\appendix| is used to signify the start of the appendixes.


\subsection{References}

References must be numbered sequentially through the text and prepared by means of \verb|\cite| and \verb|\bibitem| commands, linking citations in the text with their entry in the reference list, which is composed within the standard \verb|thebibliography| environment.

When several references occur together in the text \verb|\cite| may be used with multiple labels with commas but no spaces separating them. Thus
\\
\strut\hfill%
\verb|\cite{Zub74,Bus89,Mel00,Mry94,Sta11,Sta04}|%
\hfill\strut%
\\
would give \cite{Zub74,Bus89,Mel00,Mry94,Sta11,Sta04}. Note that labels are sorted in an ascending order and the groups of consecutive numbers are condensed.

The citation scheme for journals is: Surnames\verb|~|Initials., Journal Title (according to the standard abbreviations), Year of publication, \textbf{Vol.}, starting page (comments: e.g. in Ukrainian, unpublished, private communication, in press) \cite{Bus89,Mel00,Mry94,Sta11}. For journals without volume numbers place the issue number instead as in reference~\cite{Mry94}. The names of all authors of cited papers must be given \cite{Padova2010}. Title of journal must be abbreviated according to the ISO~4 ``\href{http://www.issn.org/services/online-services/access-to-the-ltwa/}{List of Title Word Abbreviations}'' standard (see, \textit{\href{http://woodward.library.ubc.ca/research-help/journal-abbreviations/}{UBC Science and Engineering Journal Abbreviations}} or \textit{\href{http://cassi.cas.org/search.jsp}{CAS Source Index Search Tool}} for the ready for use lists of journal titles). Please supply \href{http://www.crossref.org/guestquery/}{DOI} for the e-versions of papers if available \cite{Bus89,Mel00,Mry94,Sta11,Scient2012}.

For books, the following order is required (skip irrelevant information): Book Authors, Book Title. Book Series Vol. No., Editor(s) (Ed[s].), Publisher, Place, Year \cite{Zub74,Abr64,Olver64}. When citing conference proceedings, please add all available data such as title, date, and place of the conference as well as publisher, place, and year of publication \cite{Yuk87}.

Please add language of publication for materials which are not written in English \cite{Mel00,Sta04,Yuk87}. Indicate materials accepted for publications by adding ``(in press)'' \cite{Scient2012}. If a preprint exists of the paper not yet accepted for publication, give the e-print \href{http://arxiv.org}{arXiv} number \cite{Shv04}. Any web resources must be cited as references \cite{url2,wiki:xxx}. Please avoid references to unpublished materials, private communication and web pages \cite{han12,url2}.

It is important to confirm the accuracy of bibliographic information in references. This has become more important now that the journal is online. To ensure that the \href{http://www.crossref.org/}{CrossRef} facility can hyper-link to the articles quoted in the bibliography, \textbf{multiple references must not be used}. I.e., a list of references under the same number is not allowed: each reference has to be singly numbered. Before submitting your article, please ensure you have checked your paper for any relevant references you may have missed.

A typical numerical reference list might be \cite{Zub74,Bus89,Mel00,Mry94,Sta11,Abr64,Olver64,Sta04,Shv04,Yuk87,han12,Scient2012,url2}.

If you are not familiar with Ukrainian language, just uncomment two lines before \verb|\ukrainianpart| in the template. The necessary translation will be made by the Editorial Office.



\section{\protect\LaTeX{} and related issues}
\label{tex-issues}

The great advantage of \LaTeX{} over other text processing systems is its ability to handle mathematics to almost any degree of complexity. For this reason it prevails in major publishing houses working in the fields of physics and mathematics. However, even so brilliant tool becomes useless without necessary level of knowledge. A lot of useful (and free) information one can find at ``\TeX{} Users Group'' website
\begin{center}
	\texttt{\url{http://www.tug.org/}}.
\end{center}

``The Not So Short Introduction to \LaTeXe{}'' by Tobias Oetiker is an absolutely necessary book for beginners:
\begin{center}
	\texttt{\url{http://ctan.org/tex-archive/info/lshort/}}
\end{center}
(available in a variety of languages including Ukrainian). Ukrainian \TeX{}nicians will find a plenty of language-specific information at Andrij Shvaika's ``\TeX{} \& Ukrainian'' Web-page
\begin{center}
	\texttt{\url{https://icmp.lviv.ua/content/tex-ukrainian}}.
\end{center}


Remember, you write \LaTeX{} sources not for computers only, but for human beings also! Please make clear and fine codes! Your document must compile without errors. Do the best you can! However, some underfulls (and few small overfulls) warnings are acceptable, since the manuscript will be slightly (?) modified anyway.

Frequently good physicists (especially young scientists) have a little knowledge how to write a good-looking article. As comprehensive (and free) tutorials on the subject one can mention
%``IOP Style Guide''
%\begin{center}
%	\texttt{\url{http://www.iop.org/websupport/file_53266.pdf}}
%\end{center}
``Physical Review Style and Notation Guide''
\begin{center}
	\texttt{\url{http://publish.aps.org/files/styleguide-pr.pdf}}
\end{center}
and ``Reviews of Modern Physics Style Guide''
\begin{center}
	\texttt{\url{http://rmp.aps.org/files/rmpguide.pdf}}
\end{center}
Remember: ``\textit{Ignorantia non est argumentum}'' and ``\textit{Scientia potentia est}''!

В цих порадах описано як підготувати та надіслати статтю для публікації в журналі ``Condensed Matter Physics'' за допомогою \LaTeX{} з використанням стилю \texttt{cmpj3.sty}. Кожен надісланий рукопис повинен містити анотацію, що відображає суть дослідження. Анотація публікуватиметься окремо від статті в різноманітних бібліографічних виданнях, тому вона мусить бути повністю самодостатньою (\emph{без приміток чи нумерованих покликів}). Вельми важливі поклики можна помістити в анотацію [Thor~A.~U., et al., Condens. Matter Phys., 2004, \textbf{7}, 111]. Анотація повинна складатися лише з одного абзацу розміром до 150~слів. Присутність математичних виразів не бажана. Слід давати означення для всіх нестандартних символів та скорочень.

\keywords До шести ключових слів
