The Editorial Board of Bulletin of Cherkasy University. Series: Physical and Mathematical Sciences supports academic discussion and encourages constructive scholarly debate on published materials.

During post-publication analysis, certain shortcomings of articles may be identified, including significant or minor errors that were not, or objectively could not have been, detected during the editorial review and peer review process.

In order to minimize such situations, the Editorial Office undertakes to agree with the authors, in particular with the corresponding author, on all changes to the manuscript text introduced at the stage of editorial and publishing preparation.

An exception is made for technical corrections, including spelling, punctuation, grammar, and other editorial amendments, which do not affect the content of the scholarly material and may be introduced without additional approval.

The Editorial Office encourages authors and readers to engage in active scholarly communication, professional discussion of research results, consideration of the prospects for their practical application, and constructive comments on the argumentation, methodology, or scholarly significance of publications.

When publishing open comments, reviews, corrections, author responses, or critical remarks, the following are unacceptable:

• personal insults;

• discriminatory statements;

• biased subjective assessments;

• statements that demean authors, reviewers, editors, or the journal’s activities as a whole.
