Bibliometric networks of scientists are defined by the relationships between publications and/or their authors, implemented on the basis of lists of co-authors and bibliographic lists. Accordingly, considering scientific journals as a set of articles published in them over a certain period of time, we can talk about bibliometric networks of journals. The corresponding graph-theoretical models, called bibliometric graphs, are often used as mathematical models of bibliometric networks. The paper proposes an approach to the analysis of a network of journals using a new type of bibliometric graph, the graph of journal intersections, based on the binary operation of set intersection. The approach is demonstrated using a relatively small example of a real network of journals, data about which is contained in the information system of the All-Russian portal Math-Net.Ru. These are 63 journals from 2008-2021 that meet certain requirements and contain almost 69,000 articles by 54,000 authors.
