2026 Journal Metrics Score
1.3
Updated August 2026 · 2-year citation average from OpenAlex data
The Journal Metrics Score is the two-year mean citedness of a journal, computed from OpenAlex (CC0) data: citations received in the most recent complete year to works published in the two prior years, divided by the number of those works. Quartiles rank journals within each OpenAlex subfield by score. Data source: OpenAlex (CC0).
| Category | Quartile |
|---|---|
| Mathematical Physics | Q2 |
| Geometry and Topology | Q1 |
| Algebra and Number Theory | Q1 |
