Language of Publication
The article may be published in the Russian, English, German or French language. The editorial board may also accept papers of general theoretical interest written in the Polish, Czech, Serbian and Bulgarian languages (the papers are then translated into Russian, the translation is then provided by the Publisher). However, the editorial board gives preference to articles written immediately in Russian, English, German or French.
If you write your paper in English, you may use either American or British English, but not a mixture of these. Authors writing in their non-native language are advised to have their articles thoroughly edited by professionals with native-level proficiency in that language prior to submission.
