A scientist’s position within the ranking is determined by their D-index (Discipline H-index), a specialized adaptation of the traditional H-index that includes only papers and citation metrics specific to the examined discipline—in this case, Mathematics. This discipline-specific approach provides a more precise measure of scholarly impact within the relevant research field.
Scope of Research and Eligibility Criteria
We examined a total of 279,971 scientist profiles drawn from a diverse array of bibliometric data sources spanning all academic disciplines. Of these, 26 scientists specializing in Mathematics within Saudi Arabia met the criteria for inclusion in the ranking.
To qualify, a candidate’s D-index needed to be at least 30, with the majority of their tier publications falling within the area of Mathematics. In addition to bibliometric performance, researchers’ awards and recognized achievements in the mathematical sciences were carefully considered. The D-index threshold is calibrated dynamically, increasing in increments of 10 contingent upon the total estimated number of scholars in each discipline. This approach ensures that the top 1% of leading experts in Mathematics are included while maintaining rigorous standards of excellence.
Furthermore, to safeguard the disciplinary relevance of the ranking, a proximity criterion requires that the gap between a scientist’s general H-index and their D-index is no greater than 30%. This ensures that the mathematicians featured are actively and predominantly contributing to the discipline of Mathematics.
Verification and Additional Considerations
Recognizing that raw bibliometric data alone cannot fully capture the quality or significance of a researcher’s contributions, the Research.com team implemented extensive manual verification practices. Each scientist’s profile was cross-referenced against publications documented in a wide range of reliable, peer-reviewed journals and conference proceedings to confirm accuracy and disciplinary relevance.
Although the number of papers published in prominent journals and conferences does not directly influence the ranking position, it serves as a valuable secondary indicator of a researcher’s scholarly contributions and leadership within Mathematics.
The primary position in the ranking remains firmly anchored in the D-index as calculated from OpenAlex and CrossRef data, both of which are considered the foremost bibliometric databases globally. We encourage readers to consult our methodology page for a comprehensive and detailed exposition of the processes and criteria used to produce this ranking.
Research.com’s Mission and Vision
The overarching goal of Research.com in producing this ranking is to inspire researchers, academic institutions, companies, and policymakers worldwide to gain insight into where the leading experts are directing their efforts. By providing an authoritative resource listing the preeminent mathematicians in Saudi Arabia, we aim to facilitate connections and collaborations, support evidence-based policy decisions, and promote excellence in scientific research.
