Top Research Topics at Operators and Matrices?

Operators and Matrices generally zeroes in on subjects such as Pure mathematics, Combinatorics, Mathematics Subject Classification, Algebra and Mathematical analysis. The Pure mathematics works featured in Operators and Matrices incorporate elements from Matrix (mathematics), Eigenvalues and eigenvectors and Bounded function. The journal focused on Mathematics Subject Classification research but expanded to cover Toeplitz matrix.

  • Pure mathematics (52.34%)
  • Combinatorics (16.12%)
  • Mathematics Subject Classification (16.12%)

What are the most cited papers published in the journal?

  • Algebraic properties of truncated Toeplitz operators (184 citations)
  • Self-adjoint Extensions of Restrictions (120 citations)
  • Singular value inequalities for matrices with numerical ranges in a sector (56 citations)

Research areas of the most cited articles at Operators and Matrices:

The published articles are mainly concerned with subjects like Pure mathematics, Mathematics Subject Classification, Matrix (mathematics), Algebra and Mathematical analysis. The most cited publications with studies in Pure mathematics featured incorporate elements of Structure (category theory), Spectrum (functional analysis) and Combinatorics. The works on Mathematics Subject Classification tackled in the most cited articles bring together disciplines like Type (model theory), Characterization (mathematics), Hausdorff space, Operator theory and Toeplitz matrix.

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

  • Mathematical analysis
  • Algebra
  • Hilbert space

The previous edition focused in particular on these issues:

The main points discussed in the journal deals with Pure mathematics, Combinatorics, Algebra, Inequality and Type (model theory). Topics in Pure mathematics were tackled in line with various other fields like Matrix (mathematics) and Spectrum (functional analysis). Topics in Combinatorics explored in it were investigated in conjunction with research in Positive-definite matrix and Class (set theory).

It connects the study in Class (set theory) with the closely related area of Bounded function. Algebra study tackled is connected to the field of Algebra over a field. The study on Inequality presented in the journal intersects with the topics under Product (mathematics).

The most cited articles from the last journal are:

  • New determinantal inequalities concerning Hermitian and positive semi-definite matrices (3 citations)
  • The generalized Crofoot transform (3 citations)
  • The norm of an infinite L-matrix (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 Operators and Matrices (based on the number of publications) are:

  • Don Hadwin (15 papers) published 1 paper at the last edition, 1 less than at the previous edition,
  • Ilya M. Spitkovsky (9 papers) absent at the last edition,
  • Hwa-Long Gau (7 papers) absent at the last edition,
  • Harald K. Wimmer (6 papers) absent at the last edition,
  • Eungil Ko (6 papers) absent 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 Operators and Matrices (based on the number of publications) are:

  • College of William & Mary (5 papers) absent at the last edition,
  • Technical University of Berlin (3 papers) absent at the last edition,
  • University of Reading (2 papers) absent at the last edition,
  • Dresden University of Technology (2 papers) absent at the last edition,
  • University of Connecticut (2 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, 100.00% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, nan% were posted by at least one author from the top 10 institutions publishing in the journal. Another nan% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included nan% of all publications and nan% 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.
