About Khayyam Journal of Mathematics

Khayyam Journal of Mathematics — Journal Profile

The Khayyam Journal of Mathematics (shortened title Khayyam J. Math.) is a peer-reviewed research journal of mathematics published by the Department of Mathematics at Ferdowsi University of Mashhad in Iran. It takes its name from Omar Khayyam, the Persian mathematician, astronomer and poet of the eleventh and twelfth centuries whose work on algebra and on the theory of equations was done in the same Khorasan region of north-eastern Iran where Mashhad now stands — a namesake that announces the journal's character: a mathematics journal rooted in a long regional tradition, publishing modern research for an international readership. Its registered identifier is electronic ISSN 2423-4788, which appears on this JournalsWorld record, in the Directory of Open Access Journals (DOAJ) record for the title, and in the OpenAlex source record resolved from that ISSN. Volume numbering in the citing literature runs from the journal's first volume in 2015 to Volume 11 in 2025, and recent volumes run to two issues a year.

Identity and history

The Khayyam Journal of Mathematics is a departmental university journal: its publisher of record in the SCImago-derived listings is the Department of Mathematics at Ferdowsi University of Mashhad, and DOAJ records the university itself as publisher. Ferdowsi University of Mashhad is one of Iran's major research universities, and its mathematics department runs more than one journal — a stable, institutionally anchored home of the kind that keeps a specialist journal alive without commercial backing. The journal's own timeline can be reconstructed from its volume numbering, which is the most reliable public evidence for a journal of this shape: papers in the citing literature appear in Volume 6 in 2020, Volume 9 in 2023, Volume 10 in 2024 and Volume 11 in 2025, which places Volume 1 in 2015, in agreement with the coverage span (2015 onwards) in the Scopus-derived listings for the title and with the earlier JournalsWorld record for this post, which reported coverage of 2015 to 2025. DOAJ added its record for the journal in February 2018, an early mark of the journal's open access standing.

The name deserves a sentence of its own, because it is doing real work. Omar Khayyam (1048–1131), born in Nishapur in Khorasan, gave his name to results and objects that mathematics students still meet — his geometric treatment of cubic equations is a landmark in the history of algebra — and a journal from Mashhad, in the same historic region, that publishes functional analysis, operator theory and algebra is claiming that inheritance deliberately. Directory users should nonetheless file the journal by its identifier, not its poetry: its e-ISSN, 2423-4788, is unique to it, while its name is shared with the many institutions, prizes and lecture series that honour Khayyam across Iran and beyond. There is no print ISSN recorded for the title in DOAJ, and authors asked by a form for a print ISSN should enter the electronic one and note that the journal is an electronic publication.

Scope and subjects

Khayyam is a general mathematics research journal with a visible centre of gravity in analysis and algebra. The DOAJ record gives its keywords as combinatorics, commutative algebra, group theory, topological groups, functional analysis and operator theory, and files it under the Library of Congress heading for Mathematics in general. The OpenAlex topic profile of its published output tells the same story from the citation side, with its largest groupings in approximation theory and sequence spaces, mathematical inequalities and applications, advanced Banach space theory, nonlinear differential equations analysis, holomorphic and operator theory, and mathematical functions and polynomials. Its published papers in the citing literature match that profile: work on commuting graphs and graph energies from algebra, on Morrey spaces and Calderón–Zygmund operators from harmonic analysis, on derivations on algebras from functional analysis, and on geometry of contact structures from differential geometry all appear under its name in recent volumes.

In submission terms, the journal is a home for original research across pure mathematics — algebra, analysis, geometry, topology, combinatorics and the parts of applied mathematics that speak to that community, such as differential equations and inequalities — presented as mathematics, with theorems, proofs and the field's normal apparatus of rigour. It is not a mathematics-education journal, not a statistics or computer-science journal, and not a venue for engineering applications with a mathematical garnish; a paper whose contribution is a model of a physical system belongs elsewhere unless its mathematical content is itself the contribution. The breadth inside pure mathematics is real, though: the same volume can carry operator theory and graph theory, and authors in any branch of pure mathematics whose work is too specialist for the large general titles and too strong for a purely local outlet are this journal's natural constituency.

Editorial process, peer review and ethics

The journal is a peer-reviewed research journal published from a university mathematics department, and its submission and review process is described on its own site, kjm-math.org, to which DOAJ's record points authors for the journal's process, aims and scope, and notes for authors. This profile states only what the fetched records verify, and authors should take the mechanical rules — manuscript preparation, file formats, and the department's current submission route — from that site directly, because departmental journal pages are revised in place and a directory copy ages badly. Two standing facts can be given firmly. First, the journal's DOAJ record states that it does not operate plagiarism screening as a recorded service — a point reported here neutrally, as DOAJ records it, and one that places the ordinary responsibility for originality squarely where mathematics journals have always placed it: on authors, referees and editors, in a field where prior work circulates openly as preprints and duplication is quickly visible to the community. Second, the journal publishes under a Creative Commons Attribution-NonCommercial licence, recorded by DOAJ, so its articles circulate freely for scholarly use with attribution. Editorial board membership for a journal of this kind is drawn from the international mathematics community — the Granada mathematician Antonio Peralta's public curriculum vitae, for example, lists membership of this journal's editorial board alongside those of much larger analysis titles — and authors should consult the board list on the journal's own site for the current roster rather than relying on any directory.

How to submit

Submissions are made through the journal's own website, kjm-math.org, following the process and author notes published there, to which the DOAJ record links. The practical expectations for a mathematics journal of this type are standard and worth stating for authors new to the field's customs: prepare the manuscript in English, in a mathematical typesetting format the journal's instructions specify, with an abstract and references in the house style; expect refereeing by specialists in the paper's branch of mathematics, with timelines governed by referee availability in a small field rather than by a publisher's service targets; and expect, if the paper is accepted, publication in one of the two issues of the current volume year. No fee stands in the way at any stage: DOAJ records that the journal has no article processing charge, which makes Khayyam one of the shrinking number of genuinely free-to-publish, free-to-read mathematics journals — a model sustained by its university department rather than by authors or readers.

Metrics and indexing

This journal's metrics require unusual care, because its databases disagree in ways that reveal coverage rather than quality. The OpenAlex source record resolved directly from its e-ISSN (source S4306517395, checked October 2026) counted 108 works and 237 citations, with summary statistics of an h-index of 7, an i10-index of 6 and a two-year mean citedness of 0.0 — but that record's counted coverage runs only from 2013 to 2021, and the journal demonstrably published Volumes 9, 10 and 11 in 2023, 2024 and 2025, so the OpenAlex figures describe a partial window and understate the journal's full output. The earlier JournalsWorld record for this post, built from Scopus-derived data, reported an h-index of 14 and coverage of 2015 to 2025; SCImago's listings for the title place it in the Mathematics (miscellaneous) category in the fourth quartile, with an SJR of 0.184 in the SCImago table fetched for this profile. These are the honest figures, each tied to its source: a small, specialist, fourth-quartile mathematics journal whose citation counts are modest in the way of most pure-mathematics titles, where papers accrue citations slowly and a journal's value lies in being a trusted venue for its community rather than in a headline metric. No Journal Impact Factor is claimed in this profile, and none should be inferred from the SJR or h-index figures given.

On indexing and discovery, the verifiable statements are these. The journal is listed in DOAJ, with a record created in 2018, which certifies its open access arrangements, its lack of author charges and its licensing as recorded there. Its Scopus-derived presence underlies the SCImago listing and the earlier record for this post. Its own website is its primary archive and the place where its current volumes appear. Authors whose institutions require a specific database listing should verify that listing in the database itself at submission time, as with every journal in this profile series.

Access and charges

Khayyam is open access: its articles are published under the Creative Commons Attribution-NonCommercial 4.0 licence (CC BY-NC) recorded by DOAJ, and are freely readable on the journal's website. On the author side, DOAJ records plainly that the journal has no article processing charge — there is no APC to budget for, and OpenAlex likewise records no APC figure for the source. For mathematics authors, whose grants rarely carry publication funds, that combination — free to read, free to publish, university-sustained — is the journal's most distinctive practical feature, and it is stated here as DOAJ records it rather than as an inference.

Is this journal right for your paper?

Khayyam is a sensible home for a solid original result in pure mathematics — in functional analysis, operator theory, algebra, approximation theory, inequalities, differential equations or a neighbouring branch — that needs a peer-reviewed, openly readable journal with an established departmental home and a decade of continuous volumes behind it. It suits authors who value the no-fee, open access model and a readership of working mathematicians over headline metrics, and it has a natural affinity for the strong mathematics communities of Iran and the wider region as well as for international authors in its core subjects, as its editorial board and citing literature show. It is a weaker fit for applied work whose home discipline is engineering or the sciences, for mathematics education research, and for authors whose promotion rules require a high-quartile or impact-factor title. Judged on its own terms — a university department's journal, named for the region's great mathematician, publishing real mathematics openly and without charge since 2015 — it does its job with a clarity of purpose that larger operations might envy.

What publishing here signals

Specialist mathematics journals live inside a reputation economy that outsiders often misread, and Khayyam's record is a clean example of why the naive readings fail. Its citation counts are small because pure mathematics cites slowly and sparsely: a strong paper in Banach space theory or commutative algebra may gather its citations over a decade, from a worldwide community of perhaps a few hundred active specialists, and a journal that serves several such communities at once will never post the counts of a biomedical or engineering title. What its record does show is the infrastructure of trust that mathematicians actually use. It has appeared without interruption from 2015 to at least 2025, volume after volume, from a named department of a major university. It was examined and listed by DOAJ in 2018, early in its life, with its licensing and its no-charge status on public record. Its papers are cited in the ordinary literature of their fields — the reference lists of journals in analysis, algebra and geometry carry its volumes 6, 9, 10 and 11 as working citations, which is the field's own verdict that the papers are real contributions being built upon. And its editorial board, as the one membership traced for this profile shows, includes established mathematicians whose names also appear on the boards of long-standing international analysis journals. None of that adds up to a high-impact title, and this profile does not pretend otherwise; it adds up to a legitimate, stable, community-recognised venue, which is what most working mathematicians need for most of their papers. Authors weighing Khayyam against a newer, glossier, fee-charging title with no volume history would do well to weigh those facts in that order: continuity first, listing second, community third, and headline metrics last — the order in which the journal's own record is strongest.

Similar and related journals

Authors comparing outlets for pure mathematics commonly weigh Khayyam against the other Iranian university mathematics journals, against regional analysis and algebra titles, and against the large international general mathematics journals where acceptance is far harder and timelines far longer. Inside this directory, its closest neighbours are the other Iranian mathematics titles published from university departments — journals of mathematical sciences and informatics, of numerical analysis and optimisation, and the Bulletin of the Iranian Mathematical Society — each with its own scope and ISSN. None of them is this journal, and none shares its identifier. Cite by ISSN — 2423-4788 — and submit through kjm-math.org, and the distinctions hold.
