Acta Universitatis Sapientiae, Mathematica: A Complete Journal Guide

Overview

Acta Universitatis Sapientiae, Mathematica is a peer-reviewed, open-access scientific journal devoted to original research across pure and applied mathematics. It is one of the subject series of Acta Universitatis Sapientiae, the scientific journal of the Sapientia Hungarian University of Transylvania, an independent Hungarian-language university in Romania. The journal publishes original research papers and surveys in English, serving mathematicians working in analysis, algebra, combinatorics, differential equations, probability, and computational mathematics. Its standard abbreviation is Acta Univ. Sapientiae Math., and it carries the print ISSN 1844-6094 and the online ISSN 2066-7752.

The journal is part of a family of series that also includes Informatica, Philologica, Agriculture and Environment, Economics and Business, Film and Media Studies, and others. In December 2013 the university signed a publishing agreement with De Gruyter under which six of the Acta series were published through De Gruyter Open, substantially widening the international visibility of the journals. The Mathematica series continues to be issued under the university's Scientia Publishing House imprint, with digital distribution through De Gruyter's Sciendo platform and long-term digital preservation through Portico.

Published semi-annually (two issues per year), the journal has been in continuous publication since 2009, when Volume 1 appeared, and each volume since has carried two issues with a steady output of research articles. It is indexed in Scopus and the Web of Science, and bibliographic aggregators attribute to it a 2025 impact factor around 1.05 (SciJournal), an SJR score near 0.27, and an h-index in the 11–16 range depending on the database snapshot. The journal's best reported quartile is Q3 in Mathematics (miscellaneous). All of these figures are directory-reported snapshots and should be verified against the live Scopus, Web of Science, and SCImago databases, since metrics move with each annual release. Because aggregator snapshots can lag behind the live databases by a year or more, the most reliable current figures will always be those shown in Scopus, the Journal Citation Reports, and SCImago on the day of checking.

Publication History

The Acta Universitatis Sapientiae journal family was founded by the Sapientia Hungarian University of Transylvania to provide a publication venue for the university's research community and for international contributors writing in English. The Mathematica series began with Volume 1 in 2009, publishing two issues per year from the outset. Early volumes carried papers on number theory, matrix theory, functional analysis, and differential equations, establishing the series' identity as a generalist mathematics journal with strengths in analysis and discrete mathematics.

A significant milestone came in December 2013, when the university entered a partnership with De Gruyter, one of the world's oldest academic publishers. Under that agreement, six series of the journal — Mathematica, Informatica, Agriculture and Environment, Philologica, Film and Media Studies, and Economics and Business — were published through De Gruyter Open, the publisher's open-access platform (now integrated into Sciendo). The partnership gave the series professional production, DOI assignment, and placement in De Gruyter's distribution channels, and it remains a defining feature of the journal's publishing model.

The series has published continuously since 2009. Volume 10 appeared in 2018, Volume 11 in 2019, Volume 12 in 2020, and Volume 13 in 2021, with subsequent volumes continuing the semi-annual rhythm. Scopus coverage of the journal is reported by directory aggregators for the period 2014–2021 in one snapshot and as ongoing in others; readers tracking citation metrics should confirm the current coverage window in Scopus directly, since aggregator snapshots can lag.

Publisher and Ownership

The journal is owned and published by the Sapientia Hungarian University of Transylvania (Sapientia EMTE), which describes itself as the independent university of the Hungarian community in Romania, dedicated to providing Hungarian-language higher education and performing scientific research at a high professional level. The publishing imprint is the Scientia Publishing House. The journal's editorial office is located at RO 400112 Cluj-Napoca, Romania, Str. Matei Corvin nr. 4, and the contact address given on the journal's site is acta@acta.sapientia.ro.

Production and online distribution are handled through De Gruyter under the 2013 agreement, with the series appearing on the Sciendo platform. The journal is published in English, which, together with the De Gruyter distribution, positions it as an international outlet rather than a regional Hungarian-language periodical. According to the journal's front matter, the Editor-in-Chief of the Acta Universitatis Sapientiae journal family is László Dávid, supported by a main editorial board whose members include Zoltán Kása, András Kelemen, Ágnes Pethő, Laura Nistor, and Emőd Veress. Series-specific editorial appointments are not publicly detailed on the pages consulted for this guide; prospective authors should confirm the current series editors on the journal's official site before submitting.

Aims and Scope

The journal aims to advance mathematics through the publication of rigorous and innovative original research, covering both theoretical developments and practical applications. Its scope spans mathematical analysis, computer science, probability theory, pure and applied algebra, differential equations, and combinatorics. Within these broad areas, the journal's published content clusters around several recurring themes: fixed point theory and its applications in metric spaces, differential equations, and optimization; functional analysis and operator theory, including inequalities for operators and operator means; algebra and matrix theory; graph theory and combinatorics, including graph energies and spectral graph theory; nonlinear and fractional differential equations and dynamical systems; and numerical methods and computational mathematics.

The journal publishes original research articles and survey papers. Representative contributions from its archive include A. Iványi's "Density of safe matrices" (2009), M. Tărnăuceanu's work on finite groups with a certain number of cyclic subgroups (2018), S. S. Dragomir's "Multiplicative inequalities for weighted arithmetic and harmonic operator means" (2019), O. P. Ahuja, A. Çetinkaya, and V. Ravichandran's "Harmonic univalent functions defined by post quantum calculus operators" (2019), S. Pirzada and co-authors' "On graphs with minimal distance signless Laplacian energy" (2021), and F. Ayant and D. Kumar's "Fredholm type integral equation with special functions" (2018). This selection illustrates the journal's characteristic blend of classical analysis, algebra, and discrete mathematics, with contributors drawn from Europe, Asia, and beyond.

Editorial Leadership

Editorial governance of the journal family rests with the Editor-in-Chief, László Dávid, and the main editorial board of Acta Universitatis Sapientiae (members Zoltán Kása, András Kelemen, Ágnes Pethő, Laura Nistor, and Emőd Veress, per the journal's front matter). Each series of the Acta family, including Mathematica, operates with its own series-level editorial arrangements under this umbrella. The current roster of series editors, associate editors, and the international editorial board for the Mathematica series could not be verified from the official pages consulted during research for this guide and is therefore left unstated here; authors and readers should consult the live journal site for the up-to-date masthead.

What is verifiable is that the journal draws its authorship internationally: recent volumes list contributors affiliated with institutions in Romania, Hungary, India, Turkey, Iran, Algeria, and elsewhere, reflecting the English-language, open-access positioning of the series. The peer-review process is reported by directory aggregators as single-blind; this is a directory-reported detail rather than a statement from the journal's own published policy pages, and the journal's exact review model, typical turnaround times, and acceptance rate are not publicly disclosed on the official site. Acceptance-rate figures (one aggregator reports around 51%) and time-to-publication estimates (around 10 weeks per one aggregator) are crowdsourced or estimated values and should be treated as indicative only.

Peer Review and Editorial Process

Like the other series in the Acta family, the Mathematica series is a peer-reviewed journal: manuscripts are evaluated by referees before acceptance. Directory sources describe the review model as single-blind. The journal's own site does not publish a detailed editorial workflow, reviewer guidelines, or average decision times, so authors should direct process questions to the editorial office at acta@acta.sapientia.ro. The De Gruyter/Sciendo production workflow provides copyediting, DOI registration, and online-first-style hosting on the publisher platform, consistent with contemporary open-access journal practice.

Because the journal is published in English and distributed internationally, manuscripts are expected to meet international standards of mathematical exposition: complete proofs, precise statements, proper citation of prior work, and clear English. Survey articles are welcome alongside original research, and the journal's archive shows a willingness to publish substantial papers — many articles run to 15–25 pages — which suits the development of extended arguments in analysis and algebra.

Indexing and Abstracting

The journal is indexed in Scopus and the Web of Science, according to directory aggregators. Its long-term digital preservation is handled through Portico, where the series is listed as preserved with ISSNs 1844-6094 and 2066-7752 under De Gruyter. The journal is also distributed through the Sciendo platform, which provides DOI-linked full texts. Readers should verify the current indexing status in Scopus and the Web of Science Master Journal List, since aggregator-reported coverage windows (for example, Scopus coverage 2014–2021 in one snapshot) can become outdated.

Metrics and Rankings

Bibliometric indicators for the journal vary by source and snapshot date; all figures below are attributed to their reporting directories and are not independently verified by this guide:

• Impact Factor: SciJournal reports a 2025 impact factor of 1.050, up from 0.640 in 2024, with a historical range from 0.156 (2016) to 1.050 (2025). ResearchBite reports an "impact score" of 0.45 for the 2022–2023 window.
• SJR: SciJournal reports an SJR of 0.267 (2025); ResearchBite reports 0.253; countryofpapers reports 0.275 with a Q3 ranking in Mathematics (miscellaneous).
• h-index: Reported between 11 (ResearchBite, Editage) and 16 (SciJournal) depending on the database and snapshot.
• CiteScore / SNIP: Editage reports a CiteScore of 1.2 and a SNIP of 0.93.
• Quartile: Q3 in Mathematics (miscellaneous) per ResearchBite and countryofpapers.

These figures place the journal in the mid-range of generalist mathematics journals: a legitimate, indexed venue with modest citation impact. Authors should treat aggregator figures as background and confirm current metrics in Journal Citation Reports and SCImago before citing them in evaluations.

Open Access, Ethics, and Archiving

The journal is published open access through De Gruyter's Sciendo platform, with full texts freely available in PDF. One directory source describes the license as CC BY-NC-ND; this is a directory-reported detail and readers should confirm the current license statement on the article pages themselves. Long-term preservation is secured through Portico, where the series is listed as preserved. As a university-published journal distributed by a major academic publisher, the series operates within standard scholarly publishing ethics; the journal's own published ethics and malpractice statements were not located on the official pages consulted, so authors with questions about plagiarism screening, authorship criteria, or corrections policy should contact the editorial office directly.

Submission Guidelines

Manuscripts are submitted to the editorial office; the journal family's contact address is acta@acta.sapientia.ro. Papers must be written in English and should present original, previously unpublished research. While the Mathematica series does not publish a detailed author-instructions page on the sections of the site consulted, the Acta family's general expectations — English-language manuscripts, original work not under consideration elsewhere, and international standards of mathematical writing — apply. Prospective authors are advised to consult the current series page on acta.sapientia.ro and the Sciendo journal page for up-to-date submission mechanics, formatting requirements, and any article-processing or publication charges (no APC is advertised on the pages consulted, but fee policies can change).

Reading the Journal Strategically

For readers, the journal's online archive on acta.sapientia.ro and Sciendo offers complete volumes from 2009 onward, with articles grouped by volume and issue and full texts in PDF. The archive is a useful resource for researchers in fixed point theory, operator inequalities, graph theory, and special functions, areas in which the journal has published consistently. Because the journal is generalist, browsing by volume rather than by keyword can surface relevant work in neighboring subfields. Citation tracking through Scopus and Google Scholar is the most reliable way to follow the influence of individual papers, given the variation in aggregator metric snapshots.

Librarians and researchers evaluating the journal for collection or citation purposes should note three durable strengths: the unbroken publication record since 2009, the major-publisher distribution and Portico preservation that guarantee long-term citability, and the genuinely international authorship that keeps the content from being parochial. The journal's DOI assignment through De Gruyter means every article carries a persistent identifier, so citations resolve reliably even as the university's own site evolves.

The University Behind the Journal

Understanding the publisher helps readers place the journal. The Sapientia Hungarian University of Transylvania (Sapientia EMTE) is the independent university of the Hungarian community in Romania. It operates faculties in Cluj-Napoca, Miercurea Ciuc, and Târgu Mureș, and its stated mission combines Hungarian-language higher education with scientific research at a high professional level. The Acta Universitatis Sapientiae journal family is the university's flagship scholarly periodical, published across a dozen subject series that mirror the university's academic profile — from mathematics and informatics through philology, economics, film and media studies, agriculture, and the social sciences.

The Scientia Publishing House is the university's publishing arm and the imprint under which the Acta series appear. The 2013 agreement with De Gruyter was explicitly framed by the university as a move to increase the recognition and reputation of its research output, placing the series on an international distribution platform while retaining university ownership. For authors, this hybrid model — university-owned, major-publisher-distributed — combines the accessibility of a university journal with the discoverability of a commercial platform: articles receive DOIs, appear in De Gruyter's discovery channels, and are preserved in Portico, the same preservation service used by the publisher's flagship journals.

Position in the Mathematics Publishing Landscape

Generalist mathematics journals that are open access, English-language, and indexed in Scopus and Web of Science occupy an important niche: they give researchers — particularly those outside the best-funded institutions — a legitimate, discoverable venue for solid, specialized work that may not fit the narrow scope of a top-tier specialty journal. Acta Universitatis Sapientiae, Mathematica fits this description. Its citation metrics are modest, but its indexing, DOI assignment, Portico preservation, and consistent publication record since 2009 distinguish it from ephemeral or predatory outlets.

The journal's thematic concentrations are worth noting for prospective authors. Fixed point theory and operator inequalities form a clear core: the archive contains extended treatments of contractive mappings, operator means, and integral equations that suggest an editorial affinity for classical analysis with modern extensions. Graph theory and combinatorics form a second pillar, with papers on graph energies, Laplacian spectra, and combinatorial structures appearing regularly. Authors working in these areas will find a readership already attuned to their problems. Conversely, researchers in highly specialized niches — say, algebraic topology or stochastic PDEs — can still publish here under the journal's generalist remit, but should frame their introductions to be accessible to the journal's broad mathematical audience.

For early-career researchers, the journal offers a credible indexed venue with a straightforward university-publisher model and no advertised author fees on the pages consulted. For readers, the freely available archive is a genuine research resource: because the journal publishes substantial papers rather than short notes, its articles often contain the full development of an argument, making them useful as expository references as well as original contributions.
