Overview

Top Research Topics at Hardy–Ramanujan Journal?

The journal tackles a plethora of topics, such as Combinatorics, Pure mathematics, Algebra, Discrete mathematics and Riemann zeta function. The research on Combinatorics featured in it combines topics in other fields like Function (mathematics) and Upper and lower bounds, Mathematical analysis. Topics in Function (mathematics) explored in Hardy–Ramanujan Journal were investigated in conjunction with research in Arithmetic function and Distribution (number theory).

Topics in Pure mathematics were tackled in line with various other fields like Series (mathematics) and Euler's formula. Discussions in Hardy–Ramanujan Journal are anchored in the subject of Discrete mathematics and the similar topic of Algebraic number. Most of the Riemann zeta function studies addressed also intersect with Riemann hypothesis.

Modulo research featured in it incorporates concerns from various other topics such as Partition (number theory) and Congruence relation. It holds forums on Conjecture that merges themes from other disciplines such as Elliptic function and Prime (order theory). The featured works in Dirichlet eta function and Dirichlet L-function, which all belong in the domain if Dirichlet series, also overlaps with concepts under Analytic number theory.

Research areas of the most cited articles at Hardy–Ramanujan Journal:

The journal articles are organized to reinforce research efforts on Pure mathematics, Combinatorics, Prime number theorem, Discrete mathematics and Hurwitz zeta function. Combinatorics research is the primary subject tackled in the published articles with a focus in Integer. Issues in Integer were discussed in the most cited papers, taking into consideration concepts from other disciplines like Arithmetic zeta function, Prime zeta function and Series (mathematics), Convergent series.

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

  • Algebra
  • Complex number
  • Mathematical analysis

The previous edition focused in particular on these issues:

The journal facilitates discussions on Combinatorics, Theta function, Prime (order theory), Pure mathematics and Ramanujan's sum. Modulo is a primary topic of Combinatorics research in it. Hardy–Ramanujan Journal addresses concerns in Prime (order theory) which are intertwined with other disciplines, such as Field (mathematics), Riemann hypothesis and Corollary.

While Pure mathematics is the focus of the journal, it also provided insights into the studies of Arithmetic function and Fourier transform. The research on Ramanujan's sum tackled can also make contributions to studies in the areas of Elliptic function, Identity (mathematics), Degree (graph theory) and Extension (predicate logic). Specifically, studies on Riemann zeta function are prevalent in the Algebra works discussed.

The most cited articles from the last journal are:

  • A heuristic guide to evaluating triple-sums (3 citations)
  • Distribution of generalized mex-related integer partitions (2 citations)
  • Partition-theoretic formulas for arithmetic densities, II (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 Hardy–Ramanujan Journal (based on the number of publications) are:

  • Shigeru Kanemitsu (8 papers) absent at the last edition,
  • R. Balasubramanian (6 papers) absent at the last edition,

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, 25.00% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 22.22% were posted by at least one author from the top 10 institutions publishing in the journal. Another 22.22% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 55.56% of all publications and 0.00% 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.
