Expositiones Mathematicae

Top Research Topics at Expositiones Mathematicae?

The discussions in the journal mainly cover the fields of Pure mathematics, Discrete mathematics, Combinatorics, Algebra and Mathematical analysis. While Pure mathematics is the focus of the journal, it also provided insights into the studies of Zero (complex analysis), Simple (abstract algebra) and Polynomial. Expositiones Mathematicae covers various topics on Combinatorics such as Integer and Conjecture.

• Pure mathematics (44.84%)

Research areas of the most cited articles at Expositiones Mathematicae:

The journal publications focus on Pure mathematics, Algebra, Combinatorics, Discrete mathematics and Mathematical analysis. The most cited articles focus on Pure mathematics as well as the interrelated topics of Dynamical systems theory. The published articles discuss concepts in Conjecture under Combinatorics and how they intertwine with disciplines like Betweenness centrality.

What topics the last edition of the journal is best known for?

• Mathematical analysis
• Algebra
• Pure mathematics

The previous edition focused in particular on these issues:

The primary areas of discussion in the journal are Pure mathematics, Combinatorics, Algebra, Polynomial and Function (mathematics). The concepts on Pure mathematics presented in the journal can also apply to other research fields, including Zero (complex analysis), Algebraic number and Variable (mathematics). Expositiones Mathematicae explores topics in Combinatorics which can be helpful for research in disciplines like Complex plane, Class (set theory), Group (mathematics) and Ternary operation.

Topics in Algebra explored in Expositiones Mathematicae were investigated in conjunction with research in Semigroup, Chain (algebraic topology), Irreducibility and Skepticism. The journal explores issues in Polynomial which can be linked to other research areas like Relation (history of concept), Tridiagonal matrix, Quantum state transfer and Piecewise. Issues in Function (mathematics) were discussed, taking into consideration concepts from other disciplines like Dimension (vector space), Simple (abstract algebra), Degree (graph theory) and Maximal function.

The most cited articles from the last journal are:

• Coefficients and higher order derivatives of cyclotomic polynomials: old and new (8 citations)
• The automorphism group of the universal Coxeter group (8 citations)
• Extinction times of an inhomogeneous Feller diffusion process: A PDE approach (3 citations)

Papers citation over time

A key indicator for each journal is its effectiveness in reaching other researchers with the papers published at that venue.

The chart below presents the interquartile range (first quartile 25%, median 50% and third quartile 75%) of the number of citations of articles over time.

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 4.26% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 11.11% were posted by at least one author from the top 10 institutions publishing in the journal. Another 15.56% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 20.00% of all publications and 53.33% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

• Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
• Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
• Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
• Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
• Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.
