Overview

Top Research Topics at Integral Equations and Operator Theory?

The discussions in Integral Equations and Operator Theory mainly cover the fields of Pure mathematics, Mathematical analysis, Discrete mathematics, Combinatorics and Algebra. The study on Pure mathematics presented in Integral Equations and Operator Theory intersects with subjects under the field of Spectrum (functional analysis). The Mathematical analysis study featured in it draws connections with the study of Eigenvalues and eigenvectors.

The journal focuses on Discrete mathematics but the discussions also offer insight into other areas such as Bounded function, Compact operator and Type (model theory). It focuses on Combinatorics as well as the interrelated topic of Hardy space. In Integral Equations and Operator Theory, Compact operator on Hilbert space and Quasinormal operator are investigated in conjunction with one another to address concerns in Operator theory research.

It features studies on Toeplitz matrix, including topics such as Toeplitz operator. The Linear subspace study tackled is a key component of adjacent topics in the area of Invariant (mathematics).

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 foci of Integral Equations and Operator Theory are Pure mathematics, Combinatorics, Bounded function, Hardy space and Hilbert space. The studies on Pure mathematics discussed can also contribute to research in the domains of Space (mathematics), Class (set theory) and Spectrum (functional analysis). In addition to Combinatorics research, Integral Equations and Operator Theory aims to explore topics under Type (model theory) and Eigenvalues and eigenvectors.

Integral Equations and Operator Theory addresses concerns in Bounded function which are intertwined with other disciplines, such as Banach space, Inverse, Omega and Domain (mathematical analysis). Topics in Hilbert space were tackled in line with various other fields like Numerical range, Linear map, Commutator (electric), Conjecture and Applied mathematics. Topics in Nonlinear system explored in Integral Equations and Operator Theory were investigated in conjunction with research in Boundary (topology) and Mathematical analysis.

The most cited articles from the last journal are:

  • The Bi-Laplacian with Wentzell Boundary Conditions on Lipschitz Domains (3 citations)
  • Dirac integral equations for dielectric and plasmonic scattering (2 citations)
  • On Semigroups Generated by Sums of Even Powers of Dunkl Operators (2 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 Integral Equations and Operator Theory (based on the number of publications) are:

  • Israel Gohberg (95 papers) absent at the last edition,
  • Marinus A. Kaashoek (49 papers) absent at the last edition,
  • Daniel Alpay (36 papers) published 1 paper at the last edition,
  • Daoxing Xia (33 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, 6.90% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 3.70% were posted by at least one author from the top 10 institutions publishing in the journal. Another 0.00% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 14.81% of all publications and 81.48% 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.
