Each university’s position within the ranking is determined by the aggregate of the D-indexes (Discipline H-index) held by its affiliated scholars, provided their principal publication field is Mathematics. It should be noted that the D-index calculation is exclusive to publications and citation data pertinent to the field of Mathematics. This approach guarantees relevance and comparability when evaluating institutional strength in the discipline.
Scope of Research and Analytical Criteria
For this edition, the methodology processed a vast dataset encompassing 279,971 scientist profiles sourced from prominent bibliometric databases. Of these, 15,282 scientists with a primary research focus in Mathematics were specifically analyzed.
To ensure exceptional rigor, a minimum D-index threshold of 30 was applied to candidate scientists, and a majority of their top-tier publications had to be firmly established in Mathematics. Additional considerations included each scientist’s awards and achievements within the field, underscoring a qualitative dimension to the bibliometric analysis.
The D-index threshold for the identification of top researchers is set in 10-point increments specific to the scale of each discipline, thus guaranteeing the inclusion of the top 1% of leading scholars. Importantly, the methodology mandates a maximum proximity of 30% between the scientist’s general H-index and their D-index, ensuring disciplinary focus. Achievements and honors further inform the evaluation of individual scholars.
Verification Practices and Methodological Integrity
The editorial team at Research.com acknowledges the inherent limitations of raw bibliometric data. As a result, all scientist profiles included in the ranking underwent manual verification, with extensive cross-correlation against publications listed in a wide spectrum of authoritative sources.
While the number of papers published in prominent journals and conference proceedings is not a ranking factor in the Research.com mathematics ranking, it is nonetheless recognized as a valuable supplementary indicator of research impact and productivity in the field.
Institutional and individual positions in the ranking utilize the H-index values as curated from OpenAlex and CrossRef — two of the most respected and comprehensive bibliometric platforms available to the academic community.
