A scientist’s position in this ranking is determined by their Discipline H-index, commonly referred to as the D-index. This metric exclusively accounts for publications and citations within the examined discipline—in this case, Mathematics—allowing for a focused and fair assessment of scientific impact in that specific research area.
Scope of Research and Qualification Criteria
The ranking evaluated a total of 279,971 scientist profiles compiled from a variety of bibliometric data sources across all disciplines. Within this broad scope, 2,000 scientists specialized in Mathematics were identified and considered for inclusion.
To qualify for the ranking, a scientist’s D-index in Mathematics had to meet a minimum threshold of 30. Additionally, the majority of their tier publications were required to be within the Mathematics discipline, ensuring the relevance of their body of work. Consideration was also given to the scientist’s awards and achievements specifically related to Mathematics, providing a qualitative complement to the citation-based metrics.
The D-index thresholds for ranking eligibility are set with increments of 10 based on the total estimated number of scholars in each discipline. This approach guarantees that the top 1% of leading scholars are consistently incorporated into the list. Furthermore, a proximity of 30% or less between a scientist’s general H-index and their D-index is required, safeguarding that a high proportion of their scholarly influence is concentrated within Mathematics.
Additional Verification Practices
The Research.com team recognizes that raw bibliometric data alone cannot serve as an absolute tool for evaluating scholarly output. As such, all scientist profiles were subjected to thorough manual verification and systematically cross-correlated with publications in a wide array of trustworthy and peer-recognized sources.
While the number of papers published in prominent journals and conference proceedings does not directly affect a researcher’s ranking position, it is regarded as a valuable secondary indicator of their contribution to the scientific community within their specific area. The position in the ranking is ultimately established using the D-index calculated from data drawn principally from OpenAlex and CrossRef, which remain the most prominent and reliable bibliometric databases accessible to researchers worldwide.
