Formatting of scientific articles is carried out in accordance with established editorial requirements set out in a separate document:
"Formatting Requirements for Articles" (TeX Template)
When preparing an article for submission, authors must adhere to the following requirements.
1. Article structure and LaTeX markup
The manuscript is submitted in LaTeX2ε format using the bmzhart class (bmzhart.cls file) and the official journal template (example.tex), which can be downloaded from the link.
Required manuscript elements and corresponding template commands:
article title in the language of the article — \title{};
authors’ surnames and initials — \author{};
ORCID of each author — \orcid{} (put in \author, as shown in the template);
institution with full address (language of the article) — \institute{};
authors’ email addresses — \email{};
abstract, title and keywords in English — \enabstract{authors}{title}{text}{keywords};
abstract, title and keywords in Ukrainian — \uaabstract{authors}{title}{text}{keywords};
MSC 2020 classification — \subjclass{};
UDC — \UDC{}.
Optional fields: \thanks{} (information about grants), \shorttitle{} (short title for headers and footers, if the main one is too long).
The language of the article is specified by the class option: [ua] for Ukrainian, [en] for English. Regardless of the language of the article, both annotations (\enabstract and \uaabstract) are mandatory.
2. Abstract
Each article must be accompanied by an abstract, which is an independent and substantive presentation of the main research results. The abstract should:
● reflect the goal, methods, main results, and conclusions of the research;
● be informative rather than merely descriptive;
● not contain literature references, tables, figures, or complex formulas;
● contain explanations of all non-standard abbreviations and notations;
● have a volume of approximately 1800 characters.
The abstract, along with the title and keywords, is the primary source for indexing the article in scientometric databases; therefore, special attention should be paid to its preparation.
3. Formatting formulas, theorems, and internal references
Formulation of formulas, theorems, and internal references
All numbered objects (formulas, theorems, statements, lemmas, consequences, definitions, remarks, examples) must have labels \label{}, and references to them must be made using the commands \ref{} or \eqref{}. Manually entering numbers in the form "formula (3)" or "Theorem 2" is not allowed.
To refer to a numbered formula, you should use \eqref{}. Formulas that are not referenced in the text must be unnumbered (\[ ... \] or equation*).
The class defines the environments theorem, proposition, lemma, corollary, remark, definition, example (and their unnumbered versions with *), so they do not need to be declared.
Labels must be unique within the article. It is recommended to use names with a prefix (\label{eq:exp-series}), indicating the type of object
(eq:, thm:, lem:, prop:, cor:, def:, rem:). A similar recommendation applies to keys in \bibitem{}: it is desirable to form them meaningfully (for example, dineen-1999, lopushansky-zagorodnyuk-2007), and not as a sequence k1, k2.
4. Bibliography and Citations
For formatting references, the command \cite must be used. Manual formatting of references in the form of [1], [2], etc., is not permitted.
General requirements:
● the list of references is presented in alphabetical order;
● all sources must be cited in the text;
● journal names are abbreviated according to AMS standards;
● for articles, the DOI must be specified (if available).
