Overview

Top Research Topics at Fixed Point Theory?

The aim of Fixed Point Theory is to expand the discussion of research in Pure mathematics, Fixed point, Fixed-point theorem, Discrete mathematics and Applied mathematics. While Fixed Point Theory focused on Pure mathematics, it was also able to explore topics like Class (set theory) and Type (model theory). In it, researchers investigate the Fixed point study as part of research in the field of Mathematical analysis.

The work on Discrete mathematics presented in the journal focuses on Fixed-point property in particular. The Applied mathematics works featured in the journal incorporate elements from Iterative method and Boundary value problem.

  • Pure mathematics (44.77%)
  • Fixed point (21.90%)
  • Fixed-point theorem (19.28%)

What are the most cited papers published in the journal?

  • Hybrid viscosity extragradient method for systems of variational inequalities, fixed points of nonexpansive mappings, zero points of accretive operators in Banach spaces (54 citations)
  • The shrinking projection method for a finite family of demimetric mappings with variational inequality problems in a Hilbert space (54 citations)
  • On orthogonal sets and Banach fixed point theorem (40 citations)

Research areas of the most cited articles at Fixed Point Theory:

The journal papers focus on Pure mathematics, Variational inequality, Mathematical analysis, Fixed point and Applied mathematics. The published articles facilitate discussions in Fixed-point theorem as part of the larger field of Pure mathematics, however, they also tackle fields such as Broad category. While work presented in the journal articles provide substantial information on Variational inequality, it also covers topics in Zero (complex analysis), Banach space and Hilbert space.

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

  • Mathematical analysis
  • Topology
  • Algebra

The previous edition focused in particular on these issues:

The objective of the journal is to combine knowledge in the areas of Pure mathematics, Applied mathematics, Fixed point, Discrete mathematics and Fixed-point theorem. It focuses on Pure mathematics but the discussions also offer insight into other areas such as Class (set theory) and Type (model theory). While work presented in Fixed Point Theory provided substantial information on Applied mathematics, it also covered topics in Operator norm and Boundary value problem.

Topics in Fixed point were tackled in line with various other fields like Locally convex topological vector space and Hilbert space. Fixed Point Theory features works in Discrete mathematics, more specifically Convex metric space, and explores their relation to disciplines like Coincidence. The Fixed-point theorem research presented in it explores the relationship between Extension (predicate logic) and the closely related topic of Poincaré conjecture.

The most cited articles from the last journal are:

  • On an equation characterizing multi-cubic mappings and its stability and hyperstability (4 citations)
  • Degree theory for discontinuous operators (3 citations)
  • Fixed point theorems in r-normed and locally r-convex spaces and applications (1 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 Fixed Point Theory (based on the number of publications) are:

  • Donal O'Regan (13 papers) published 4 papers at the last edition, 3 more than at the previous edition,
  • Jen-Chih Yao (12 papers) absent at the last edition,
  • Yekini Shehu (6 papers) published 2 papers at the last edition, 1 more than at the previous edition,
  • Adrian Petrușel (6 papers) published 2 papers at the last edition, 1 more than at the previous 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, 54.10% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 46.43% were posted by at least one author from the top 10 institutions publishing in the journal. Another 7.14% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 39.29% of all publications and 7.14% 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.
