The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.1 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.0002 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

要約

Mathematical problems, are assigned a place of paramount importance in high school as a tool for the development of thinking. The problems that were carefully selected in the course of the past two millennia were highly instrumental in developing the ability of logical deliberation, intuition and common sense.
The importance of problems is not diminished on the university level. However, their role here is different. A professional differs from an amateur, among others, by the former's understanding of the limits of his expertise. It is imperative that a specialist be able to distinguish between elementary problems, or problems that have already been solved and those in his field that still require solution. The simplest method to become versant in what "is inconvenient not to know" is to suggest a specially selected set of problems. These problems should be surprising and interesting and their solution should require a certain intellectual effort rather than elementary application of familiar theorems and methods, but at the same time be within the ability of the student.
In addition, problems allow avoiding a rather frequent situation which was aphoristically formulated by one of my students: "When you are explaining, everything is clear, when you start asking everything is incomprehensible".
