The previous edition focused in particular on these issues:

Journal of Functional Analysis is organized to address concerns in the fields of Pure mathematics, Combinatorics, Type (model theory), Mathematical physics and Mathematical analysis. Many of the research works in Pure mathematics, specifically Quasinormal operator, closely connected to disciplines like Fell. Combinatorics research featured in it incorporates concerns from various other topics such as Orthogonality, Perturbation theory, Isometry, Hardy space and Characterization (mathematics).

While work presented in Journal of Functional Analysis provided substantial information on Type (model theory), it also covered topics in Tree (set theory), Bilinear interpolation, Inequality, Rank (linear algebra) and Degenerate energy levels. The studies in Mathematical physics featured incorporate elements of Covariance, Derivative, Generator (category theory) and Gaussian measure, Gaussian. The journal focuses on Mathematical analysis but the discussions also offer insight into other areas such as Flow (mathematics), Liquid crystal and Inertia.

The most cited articles from the last journal are:

• Some sharp Schwarz-Pick type estimates and their applications of harmonic and pluriharmonic functions (1 citations)
• Quasi-invariance of low regularity Gaussian measures under the gauge map of the periodic derivative NLS (1 citations)
• Hyper-positive definite functions I: scalar case, branching-type stationary stochastic processes (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.

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 2022 edition, 20.00% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 0.00% 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 8.33% of all publications and 91.67% 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.
