Scientific Coauthorship in Russian Mathematics in 2000–2020: A Study Based on Leading Russian Journals

Scientific coauthorship is a direct reflection of scientific collaboration. There is empirical evidence of the value of coauthorship: articles with a bigger number of authors tend to be cited more often, which is important for calculating various indices. Many foreign studies show an increase in coauthorship both overall and specifically in various scientific disciplines; it is, however, quite difficult to assess the situation with coauthorship with regard to Russian scientists based on Web of Science or Scopus for a number of reasons. Based on data from Math-Net.Ru, this paper looks at some issues of coauthorship in mathematical and computer sciences in Russia. In particular, it shows a small but steady increase in the average number of coauthors per publication and an increase in the number of coauthored articles in 2000–2020.
