Scientific co-authorship is a direct reflection of scientific collaboration. There is empirical evidence of the value of co-authorship, for example, articles with a large number of authors tend to be cited more often, which is important for calculating various indexes. Many foreign studies show an increase in co-authorship both in general and in various scientific disciplines, however, it is quite difficult to judge the situation with co-authorship of Russian scientists based on research according to Web of Science or Scopus for a number of reasons. According to the portal Math-Net.Ru some issues of co-authorship in the field of mathematical and computer sciences in Russia are investigated. In particular, it shows a small but steady increase in the average number of coauthors per publication and an increase in the number of articles co-authored over the years 2000-2020.
