A researcher's position in the ranking is determined by their Discipline H-index, commonly referred to as the D-index. Unlike traditional metrics that aggregate all published work, the D-index specifically evaluates publications and citation impact within the field of Mathematics. This focused approach provides a more nuanced and accurate reflection of a scientist’s influence and standing in the discipline.
Scope of Research and Qualification Criteria
For this edition, an extensive evaluation was conducted across 279,971 scientist profiles identified from a diverse array of bibliometric data sources covering all scientific disciplines. From this large pool, 46 scientists specializing in Mathematics in the Netherlands were carefully assessed to create the ranking.
To qualify for inclusion, a scientist was required to have a minimum D-index of 30, with the majority of their tier publications demonstrably centered in Mathematics. In addition to bibliometric performance, consideration was given to notable awards and achievements within the discipline, further enhancing the robustness of the ranking criteria.
The threshold for the D-index is calibrated in increments of 10 based on the estimated total number of scholars in each discipline. This adaptive threshold guarantees that the ranking consistently represents the top 1% of leading researchers in Mathematics. Furthermore, to ensure relevance and disciplinary specialization, profiles where the difference between a scientist’s general H-index and their D-index exceeded 30% were excluded.
Verification and Methodological Integrity
Meticulous manual verification procedures complement the bibliometric data to enhance the accuracy and credibility of the ranking. Each scientist’s profile underwent rigorous cross-referencing against publications from a broad spectrum of authoritative and trustworthy sources to confirm the legitimacy of their records. This process acknowledges the limitations of raw bibliometric data and ensures that the ranking reflects genuine scholarly contributions.
While not a direct factor in determining rank positions, the volume of publications in prominent journals and conference proceedings is recognized as a valuable secondary signal of research impact and leadership within the Mathematics community.
The final ranking positions are established strictly based on the D-index calculated from bibliometric data sourced from OpenAlex and CrossRef, two of the most prominent and respected databases available to researchers worldwide.
