Overview

Top Research Topics at Journal of Noncommutative Geometry?

The journal investigates areas of study like Pure mathematics, Noncommutative geometry, Group (mathematics), Algebra and Cohomology. Journal of Noncommutative Geometry encompasses presentations on Pure mathematics, specifically Hopf algebra, Equivariant map, Cyclic homology, Functor and Spectral triple. Hopf algebra study tackled is connected to the field of Structure (category theory).

In addition to Noncommutative geometry research, it aims to explore topics under Commutative property, Torus and Dirac operator. The in-depth study on Group (mathematics) also explores topics in the intersecting field of Combinatorics. Combinatorics research presented is mostly focused on the subject of Isomorphism.

  • Pure mathematics (78.31%)
  • Noncommutative geometry (21.26%)

Research areas of the most cited articles at Journal of Noncommutative Geometry:

Pure mathematics, Noncommutative geometry, Algebra, Spectral triple and Commutative property are the main subjects of interest in the most cited papers. The most cited publications connects research in Pure mathematics with the related topics of Group (mathematics). The published articles focus on Algebra but the discussions also offer insight into other areas such as Quantum group, Mathematics Subject Classification and Filtered algebra.

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

  • Pure mathematics
  • Algebra

The previous edition focused in particular on these issues:

The primary areas of discussion in Journal of Noncommutative Geometry are Pure mathematics, Equivariant map, Homotopy, Group (mathematics) and Isomorphism. The study on Pure mathematics presented in the journal intersects with subjects under the field of Structure (category theory). The journal facilitates discussions on Equivariant map that incorporate concepts from other fields like Generalization, Locally compact group, Loop space and Signature (topology).

The work on Group (mathematics) tackled in the journal brings together disciplines like Bimodule, Abelian group and Lattice (group). Isomorphism research presented in the journal encompasses a variety of subjects, including Transfer (group theory), Manifold, K-theory and Foliation. The featured Conjecture studies mainly concentrate on Lie group but also cover areas of interest in Noncommutative geometry.

The most cited articles from the last journal are:

  • Algebraic bivariant $K$-theory and Leavitt path algebras. (5 citations)
  • Duality of Gabor frames and Heisenberg modules (5 citations)
  • A categorical characterization of quantum projective spaces (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.

The top authors publishing in Journal of Noncommutative Geometry (based on the number of publications) are:

  • Goncalo Tabuada (8 papers) absent at the last edition,
  • Piotr M. Hajac (6 papers) published 1 paper at the last edition,
  • Michel Van den Bergh (6 papers) absent at the last edition,
  • Jens Kaad (6 papers) published 1 paper at the last edition,
  • Sergey Neshveyev (5 papers) published 1 paper at the last edition.

The overall trend for top authors publishing in this journal is outlined below. The chart shows the number of publications at each edition of the journal for top authors.

Only papers with recognized affiliations are considered

The top affiliations publishing in Journal of Noncommutative Geometry (based on the number of publications) are:

  • Max Planck Society (18 papers) published 1 paper at the last edition, 1 less than at the previous edition,
  • University of Münster (9 papers) absent at the last edition,
  • University of Copenhagen (7 papers) absent at the last edition,
  • Polish Academy of Sciences (7 papers) published 1 paper at the last edition,
  • University of Göttingen (6 papers) absent at the last edition.

The overall trend for top affiliations publishing in this journal is outlined below. The chart shows the number of publications at each edition of the journal for top affiliations.

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, 4.35% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 9.09% were posted by at least one author from the top 10 institutions publishing in the journal. Another 22.73% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 31.82% of all publications and 36.36% 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.
