Abstract:
According to the portal Math-Net.Ru a graph of journal citation is
constructed. To increase the reliability of the model, the citation time interval was
chosen from 2010 to 2021, when the distribution of citation articles stabilized at the
level of 3500-4500 citations per year. The structure of link aging is studied and it is
shown that their half-life is equal to 8 years. Therefore, the publication date of the
cited articles was limited to 2002. For the constructed citation graph, the main
properties, such as a small diameter and a high density, are obtained, indicating a high
level of scientific communication in the Math-Net.Ru. Adequacy of the journal
citation graph Math-Net.Ru as a model of scientific communication confirmed by
comparing the ranking of journals in the citation graph with their SCIENCE INDEX
rating in eLIBRARY.RU. A direct moderate relationship between the two rankings is
shown. A number of meaningful conclusions are drawn from the analysis of the
citation graph.
