To determine each institution’s position in the ranking, we calculated the sum of the D-indexes (Discipline H-index) for all qualifying scholars affiliated with that institution whose primary publication area is Mathematics. The D-index measures only those publications and citations that pertain specifically to Mathematics, thus offering a precise, discipline-focused reflection of scholarly impact.
Scope of the Ranking and Criteria for Inclusion
The analysis encompassed 279,971 scientist profiles across various disciplines identified from a combination of bibliometric sources. For Mathematics specifically, 15,282 scientists were evaluated. Each scientist considered met a minimum D-index threshold of 30, with a majority of their body of work published in the area of Mathematics.
The inclusion criteria included not only the D-index, but also awards and notable achievements in Mathematics, thereby integrating qualitative indicators with quantitative metrics. For top-tier researchers, the D-index threshold was set in increments of 10, adjusted for the estimated number of scholars per discipline and ensuring the inclusion of the top 1% leading scholars. Additionally, only scientists whose D-index was within 30% of their general H-index were considered, ensuring strong disciplinary consistency.
Furthermore, recognition through major awards and contributions to the advancement of Mathematics were taken into account, emphasizing both the impact and the quality of scholarly work.
Verification Practices and Data Reliability
The Research.com team recognizes that bibliometric indicators alone cannot fully capture the depth and breadth of a scholar’s contributions. Therefore, manual verification was conducted for each scientist profile, cross-referencing records and publication lists across a wide range of reliable sources to ensure high accuracy.
Although the number of publications in prominent journals and conference proceedings does not directly affect ranking positions, it is acknowledged as a relevant secondary indicator of scientific impact and contribution. The core metric for institutional ranking is derived from each researcher’s H-index, calculated using data from OpenAlex and CrossRef—the two leading and most trusted bibliometric databases available to the research community.
