01Impact factor
Impact factor of Journal of Operator Theory (2026)
The impact factor shown here is the 2-year mean citedness: citations received in a year by the papers Journal of Operator Theory published in the two previous years, divided by the number of those papers. That is the same formula as the Journal Impact Factor, calculated by ScholarsColab. The journal is listed in JCR 2024, so it also has an official Journal Impact Factor published by Clarivate, which can differ because it counts citations from Web of Science journals only.

Ranks here compare journals of the same Web of Science category in our data by 2-year citedness; they are not the official JCR rank.
Quartile of Journal of Operator Theory
A journal's quartile (Q1 to Q4) is its position within a subject category: Q1 is the top quarter. The official quartiles are published by Clarivate in Journal Citation Reports (by Journal Impact Factor, in Web of Science categories) and by Scimago as the SJR quartile (in Scopus categories). Journal of Operator Theory is listed in JCR 2024, so its JCR quartile is in Journal Citation Reports. It is indexed in Scopus, so Scimago shows its SJR quartile. ScholarsColab does not show a quartile until it can show the official one; the impact factor and rank above are calculated from open data.

05How to submit
How to submit to Journal of Operator Theory
- Read the guide for authors. It sets the article types, word limit, reference style and file format that Journal of Operator Theory accepts. You find it on the official website of the journal, usually under "For authors" or "Submit".
- Format to the journal's style. Check whether it wants a Word file, a LaTeX file or a PDF for the first submission, and follow its reference style; many journals accept any clear format at first and ask for their style only after acceptance.
- Check the fit. Read the aims and scope and a few recent issues; papers outside the scope are the most common reason for a desk rejection. The Journal Finder shows journals that published the closest work.
- Check the fee. Journal of Operator Theory is not a fully open access journal, so authors usually pay nothing unless they choose open access for their article or the journal charges page or colour fees. The guide for authors states the current charges.
- Check your manuscript before you submit. The free Submission Readiness Check asks the seven questions our reviewers ask in every audit and takes about 2 minutes.
