In 2025, Annals of Mathematics and Physics had an OJR of 0.11: its 2022–2024 papers received 11% of the world-average citations for comparable papers. Its Impact factor (2-year) was 0.26. Both figures are calculated from OpenAlex data.
Annals of Mathematics and Physics is Q4 in OpenJournalRank’s 2025 Astronomy and Astrophysics ranking (#84 of 107 eligible journals). These are OJR quartiles, calculated independently of SCImago, Scopus and JCR quartiles.
The OpenJournalRank Indicator (OJR) is a free, publicly available metric of a journal’s field-normalized citation impact, computed from open OpenAlex citation data. It compares citations to a journal’s papers from the previous three years with the world average for papers of the same subfield, year and type, so 1.00 is the world average and values can be compared across fields. It is computed with the NCI3 method. For 2025 it counts non-self citations to the articles, reviews and conference papers a journal published in 2022–2024. Ranks and quartiles order journals by OJR within the subfield, the field and all journals.

Q4#84 of 107
The Impact factor (2-year) counts citations made in 2025 to the articles, reviews and conference papers a journal published in the two previous years (2023–2024), divided by the number of those papers. Self-citations count; citations from repository-hosted works do not. It is not normalized by field. Clarivate’s Journal Impact Factor™ uses the same basic formula but gives different numbers, and this site does not show it. Clarivate also counts citations to editorials, news and letters while dividing only by articles and reviews. OpenAlex sets document types automatically. The citing data differ: OpenAlex links references for most but not all works, and we leave out repository-hosted citing works. Publication years and snapshot dates also differ. Because of these differences, our value can be higher or lower than the JIF for a given journal, so don’t compare the two directly.

Why is it different?
- Journals usually quote Clarivate’s Journal Impact Factor™ (JIF).
- Same idea: citations this year to papers from the past two years, divided by those papers.
- The JIF also counts citations to editorials, news and letters but divides only by research papers. We count citations to research papers only.
- Different citation data (OpenAlex, not Web of Science) and timing.
So the two numbers can differ, in either direction, and the size of the difference has not been established. Compare ours with other journals here, not with the JIF.

OJR rank in each category · 2025
The badge is the quartile; Q1 is the top quarter of ranked journals. Each track runs from the bottom of the category (left) to the top (right), shaded by quartile. The bold marker is this journal and the thin tick the category median. The outlined box is the likely rank range: the 95% interval from re-drawing the journal’s papers 1,000 times. “Spans Q1–Q2” means that range crosses a quartile boundary.
Ranking categories are derived from OpenAlex paper classifications and may differ from a journal’s stated scope.

In context
How Annals of Mathematics and Physics compares with the journals of its comparison group: Physics and Astronomy. Windows are 2022–2024 (retractions 2015–2024).
Each group is the journal’s field, or its domain when the field has too few eligible journals. On each value track the shaded band is the middle half of the group and the tick its median. The percentile under it is a mid-rank position out of 100: journals with a lower value count fully and tied journals count half, so ties share a mid-rank. Colour marks only retractions, cost and an unusual self-citation share; other differences carry no quality judgement.

Integrity and cost
Retracted papers per 1,000
Papers marked retracted per 1,000 citable papers at the OpenAlex snapshot date; this does not show the reasons for retraction or assess a journal’s practices.
Comparison group too small or not enough papers for this measure.
Listed APC (USD)
The article processing charge OpenAlex lists for the source; zero means a listed charge of $0.
OpenAlex has no listed APC for this journal, so there is no cost comparison.
Check the publisher’s author guidelines for current charges.

Detailed breakdown
The figures behind the charts, written out in full.
The two headline numbers
OJR is OpenJournalRank’s index, computed with the NCI3 method. It divides the non-self citations that papers published in 2022–2024 received in 2025 by the citations expected for papers of the same subfield, publication year and type worldwide. For 2022–2024, papers in this journal received 11% of the citations expected worldwide for comparable papers.
The Impact factor (2-year) is simpler: citations made in 2025 to the papers published in 2023 and 2024, divided by the number of those papers. For this journal it was 0.26, up from 0.23 in 2024 (+11.8%). It counts self-citations and is not adjusted for field, so a value of 5 means something different in economics and in molecular biology.
This value is computed from OpenAlex and is not Clarivate’s Journal Impact Factor™. The two use different citation sources and different rules for which items count, so the numbers will not match. Across all core journals, 84.3% of articles and reviews published in 2025 have at least one matched reference in OpenAlex (87.1% in 2024). This is a corpus-wide share: it does not measure how complete any one journal’s reference lists are, and no value on this page is adjusted for it.

What it publishes
In 2022–2024, the journal published 110 citable papers (articles, reviews and conference papers).
Among papers with a subfield: 11% in Astronomy and Astrophysics, 9% in Atomic and Molecular Physics, and Optics, 6% in Geometry and Topology, 5% in Applied Mathematics, and 5% in Nuclear and High Energy Physics.
Subjects follow OpenAlex’s primary-subfield classification, which may differ from a journal’s stated scope.
Among papers with a known author affiliation country: United States (11%), China (9%), Germany (8%), Russia (8%), and India (6%). Author affiliations span 35 countries in this window. A paper counts toward each country it lists, so shares can total more than 100%.
59% of the window’s citable papers list at least one author affiliation country; country shares describe that subset.
Open-access status among papers with a known status: diamond (100%).
