 Russian mathematician stubs

"Russian mathematician stubs" usually refers to a specific kind of entry on Wikipedia that is related to a mathematician from Russia but does not contain a lot of detailed information. In Wikipedia terminology, a "stub" is a page that is very short or incomplete and can be expanded with more content. These stubs typically contain at least some basic information about the mathematician, such as their name, birth and death dates, and perhaps a few key contributions or areas of research.
