Research areas of the most cited articles at Forum of Mathematics, Sigma:

The most cited papers mainly tackle studies in Pure mathematics, Combinatorics, Abelian group, Conjecture and Applied mathematics. The studies on Pure mathematics discussed at the most cited papers can also contribute to research in the domains of Skeleton (category theory) and Algebra. The most cited articles facilitate discussions in Automorphism group and Transitive relation as part of the larger field of Combinatorics, however, they also tackle fields such as Linear growth and Alphabet.

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

• Algebra
• Pure mathematics
• Mathematical analysis

The previous edition focused in particular on these issues:

Forum of Mathematics, Sigma is organized to address concerns in the fields of Pure mathematics, Combinatorics, Type (model theory), Conjecture and Group (mathematics). While work presented in it provided substantial information on Pure mathematics, it also covered topics in Space (mathematics), Algebraic number and Moduli. The journal explores research in Combinatorics alongside concepts in Surface (topology) and other areas of study in Equivalence relation, Orbit (control theory), Compactification (mathematics), Newton polygon and Diffeomorphism.

The featured Type (model theory) research zeroes in on concepts in Cluster algebra but also tackles themes under Index (economics). The studies on Conjecture discussed can also contribute to research in the domains of Orbifold, Simple group, Fibered knot, Moduli space and Function field. The research on Group (mathematics) featured in it combines topics in other fields like Canonical bundle, Quotient and Rank (linear algebra).

The most cited articles from the last journal are:

• Higher rank K-theoretic Donaldson-Thomas Theory of points (8 citations)
• Verlinde formulae on complex surfaces: K-theoretic invariants (7 citations)
• P = W for Lagrangian fibrations and degenerations of hyper-Kähler manifolds (4 citations)

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, 44.78% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 29.73% were posted by at least one author from the top 10 institutions publishing in the journal. Another 10.81% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 29.73% of all publications and 29.73% 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.
