Impact factor of Forum of Mathematics, Sigma (2026)
The impact factor shown here is the 2-year mean citedness: citations received in a year by the papers Forum of Mathematics, Sigma 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.
Rank in its subject categories

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 Forum of Mathematics, Sigma
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).
