The position of each scientist within the ranking is determined by their D-index (Discipline H-index), a specialized metric that exclusively includes publications and citation counts within the examined discipline—in this case, Mathematics. This ensures that the ranking accurately reflects a researcher's impact and contribution specific to the mathematical sciences rather than their overall scholarly output.
Scope of Research and Qualification Criteria
The ranking evaluates 279,971 scientist profiles identified through a diverse set of bibliometric databases, covering all academic disciplines. Specifically, for the field of Mathematics, 18 scientists were examined to develop a focused and insightful ranking relevant to Korea’s leading mathematicians.
To qualify for inclusion, a researcher’s D-index must be at least 30. Additionally, a majority of their tier publications—publications in reputable and high-impact venues—must be within the area of Mathematics. Awards and recognized achievements in the mathematical sciences were also considered, serving as an additional qualitative factor in assembling the list.
The D-index threshold is carefully calibrated in increments of 10 based on the estimated total number of scholars in each discipline, ensuring that the top 1% of leading experts are included in the ranking. Furthermore, only candidates with a proximity of 30% or less between their general H-index and their D-index are considered, confirming that their scholarly reputation is strongly rooted within the discipline of Mathematics.
Additional Verification Practices
Recognizing that raw bibliometric data alone cannot fully encapsulate the quality and breadth of a scholar's contributions, all scientist profiles included in the ranking underwent manual verification. Profiles were cross-correlated against publications in a wide range of trustworthy sources to affirm accuracy and consistency.
While the count of papers published in prominent journals and leading conference proceedings does not directly influence the ranking positions, it functions as a valuable secondary signal of a scientist’s tangible contribution to mathematical research. The ranking itself is established strictly based on the D-index derived from data collected via OpenAlex and CrossRef.
These two databases are among the most prominent and well-known bibliometric resources available to researchers globally, underscoring the rigor and credibility underpinning the ranking methodology.
