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

ABSTRACT

Investigations related to some hidden symmetry properties of the system of differential equations of magnetohydrodynamics (MHD) are presented. The MHD-equations of a finite electrical conductivity characterized by the magnetic Reynolds number Rem are considered. Each model under consideration is characterized some hidden geometric and physical symmetry. As a result, it makes it possible to simplify the original model: decomposition, introduction of potentials or new variables, self-similarity et al. The MHD-system for magneto-isotropic compressible fluid under the action of a magnetic field is considered and nondi-mensionalized. It is shown that in the case of one-dimensional nonlinear motion the original system can be reduced to some simplified form. In the case of linearized equations the self-similarity analysis is applied allowing to obtain the system in which the value Rem is not involved explicitly. Approximations of a weak and high Rem are developed leading to hierarchy systems. The introduction of potentials leading to some cases of solvability is presented.
