A researcher's position within the ranking is determined by their D-index (Discipline H-index), an adaptation of the traditional H-index that exclusively accounts for publications and citation metrics specific to the examined discipline—in this case, Mathematics. This discipline-specific focus allows for a more precise evaluation of expertise and impact within the relevant scientific community.
Scope of Research and Eligibility Criteria
The foundation of this ranking is a thorough examination of 279,971 scientist profiles drawn from a broad spectrum of bibliometric data sources encompassing all scientific disciplines. Within this extensive dataset, 147 scientists specializing in Mathematics were identified and rigorously assessed.
To qualify for inclusion in the ranking, a scientist was required to meet the following criteria:
- Attain a minimum D-index of 30, ensuring that only those with a demonstrable impact within Mathematics are considered.
- A majority of their tier publications must be situated within the area of Mathematics, guaranteeing disciplinary relevance.
- Recognition of their awards and achievements within the Mathematics community also played an important evaluative role.
The D-index threshold is calibrated in increments of 10, based on the estimated total number of scholars within each discipline. This approach ensures that the ranking consistently includes the top 1% of leading researchers in the field. Additionally, to maintain rigor and coherence between general and discipline-specific impact, only those scientists whose general H-index and D-index are within approximately 30% proximity were considered eligible.
Verification and Validation Practices
We acknowledge that raw bibliometric data alone cannot serve as an absolute measure of scholarly output or research quality. To this end, every scientist profile included in the ranking was manually verified by a dedicated team of experts. This process involved cross-referencing publication records against a wide range of trustworthy sources to authenticate authorship and ensure the accuracy of citation counts.
While the primary determinant of ranking is the D-index derived from OpenAlex and CrossRef—the most widely respected and utilized bibliometric databases—other factors, such as the number of publications in prestigious journals and leading conference proceedings, were considered valuable supplementary indicators of a scientist's scholarly contributions. Although these supplementary indicators do not directly affect ranking positions, they provide meaningful context regarding a researcher’s influence and standing within the Mathematics discipline.
