A university's position in the ranking is based on the sum of D-indexes (Discipline H-index) of all ranking scholars affiliated with the institution, provided their primary publication area is Mathematics. The D-index metric is rigorously discipline-specific, utilizing only those publications and citations relevant to Mathematics. This ensures a focused and fair assessment that reflects true scholarly impact within the field.
Ranking Scope and Research Population
The underlying foundation of the ranking is built upon the analysis of 279,971 scientist profiles identified from a variety of bibliometric data sources, out of which 15,282 scientists specializing in Mathematics were subjected to further detailed examination. To be eligible, scientists were required to have a minimum D-index of 30, with the majority of their significant publications in Mathematics. Beyond quantitative metrics, notable awards and achievements in Mathematics were also taken into account.
Additionally, the D-index threshold for recognizing top researchers is dynamically adjusted in increments of 10 according to the overall number of scholars in each specific discipline. This approach ensures that the exceptional contributions of the top 1% of leading scholars are captured within the ranking. To protect the integrity of the discipline focus, a proximity criterion is applied, whereby a scholar’s overall H-index may not exceed their D-index by more than 30%. Furthermore, individual scientist awards and distinctions in Mathematics continue to enhance their profile evaluation.
Verification Practices and Data Integrity
At Research.com, we recognize that raw bibliometric data alone cannot fully encapsulate a scholar’s impact. Hence, every scientist profile in the ranking is manually verified and rigorously cross-referenced against numerous trusted sources of publication data. This meticulous verification process ensures the reliability and fairness of the results.
While the quantity of papers published in leading journals and international conferences is not directly factored into the final ranking position, it remains a valuable secondary indicator of a scholar’s consistent contribution and reputation in Mathematics. Each researcher’s ranking status is determined by the D-index, which is derived using H-index and publication metrics sourced from OpenAlex and CrossRef—two of the most respected and accessible bibliometric databases serving the global scientific community.
