This dictionary is intended for use primarily by speakers of English who need to understand Russian mathematical writing and/or to translate such writing. As far as possible, the "definitions" are translations rather than explanations, and reflect current usage in mathematical writing. The vocabulary has been extensively enlarged and brought up to date, although it retains some obsolete terms that may be needed by users who have to consult older literature. Users may encounter material that has not been composed in the most approved or correct style. Therefore, some words that are frowned on by Soviet purists have been retained, or added, because they occur in writing by Soviet authors whose native language is not Russian, and whose knowledge of Russian is less than perfect.
