Scope

The journal Mathematica was founded in 1929 at the University of Cluj by Petre Sergescu. The publication of the journal was interrupted between 1948 and 1959. Since 1959 Mathematica is published as a new series, continuing the traditions of the old one, under the auspices of the Romanian Academy. It appears in one volume a year, consisting of 2 issues with a total average number of pages yearly of 200. The journal is reviewed or indexed by Zentralblatt fur Mathematik, Mathematical Reviews, Scopus and EBSCO. Mathematica publishes original papers in any area of pure and applied mathematics. The topics cover all branches of Mathematics: Algebra, Group Theory, Lie Algebras, Logic, Combinatorics, Number Theory, Mathematical Analysis, Functional Analysis, Numerical Analysis, Potential Theory, Complex Analysis, Ordinary Differential Equations, Partial Differential Equations, Optimal Control, Geometry, Algebraic Geometry, Topology, Dynamical Systems, Probability Theory, Statistics, Mathematical Physics, Fluid Mechanics, Solid Mechanics, Calculus of Variations, Mathematical Problems in Sciences, Operational Research. In addition to research papers, Mathematica publishes proceedings of international conferences held in Romania and survey articles. The Editors will put strong emphasis on originality and applicability of the results. All manuscripts are strictly refereed and only papers of high quality are accepted for publication. The journal is addressed to all pure and applied mathematics and to other specialists interested in modern developments of mathematics and in using mathematics in research, teaching and technology.

Quartiles

The set of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. Q1 (green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orange) the third highest values and Q4 (red) the lowest values.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Cites per Doc

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.
