A scientist’s position within the ranking is determined based on their D-index (Discipline H-index). This metric is discipline-specific, considering only publications and citation counts directly related to the field of Mathematics. As such, the D-index provides a focused and meaningful evaluation of a researcher’s impact within the examined subject area, rather than a broader interdisciplinary measure.
Scope of Research and Inclusion Criteria
The ranking is grounded in an extensive examination of 279,971 scientist profiles drawn from a diverse array of bibliometric data sources across all disciplines. Within this dataset, 230 scientists specializing in Mathematics were identified and evaluated. To qualify for inclusion in the ranking, scholars were required to meet a minimum D-index threshold of 30, reflective of significant scholarly influence within Mathematics. Furthermore, the majority of each qualifying scientist’s tier publications had to be concentrated in Mathematics, ensuring the discipline relevance of their output.
In addition to bibliometric measures, scientists’ awards and achievements within Mathematics were also taken into consideration as part of the assessment process. The D-index threshold used to delineate top researchers is adjusted in increments of 10 relative to the estimated total number of scholars in each discipline, a formula designed to secure representation of the top 1% of leading experts. Moreover, to ensure discipline-centricity, a scientist’s general H-index and D-index must be within 30% or less of each other, minimizing disparities driven by contributions outside the field.
Additional Verification and Methodological Rigor
Recognizing that raw bibliometric data alone cannot fully capture the nuances of scholarly contributions, the Research.com team implemented rigorous additional verification procedures. All scientist profiles were manually verified and cross-correlated against publications indexed in a broad spectrum of trustworthy sources, thereby strengthening the accuracy of author identification and attribution.
While not influencing a researcher’s ranking position, the number of papers published in prominent journals and leading conference proceedings serves as a valuable secondary signal of scientific contribution within Mathematics. Ultimately, the ranking position is established exclusively through each researcher’s D-index, based on curated data from OpenAlex and CrossRef — two of the most prominent and authoritative bibliometric platforms globally.
