A scientist's position in the ranking is determined based on their D-index (Discipline H-index), a metric that specifically accounts for papers and citations within the discipline under examination—in this case, Mathematics. This focus on discipline-specific metrics enables a more nuanced and relevant evaluation of a researcher’s impact within their core area of expertise.
Scope of Research and Eligibility Criteria
The ranking process involved the examination of 279,971 scientist profiles aggregated from a variety of bibliometric databases covering all scientific disciplines. Specifically, 171 scientist profiles related to Mathematics were identified and assessed in detail for inclusion.
To qualify for the ranking, a scientist was required to have a D-index of at least 30, with a majority of their tier publications focused in the domain of Mathematics. In addition to bibliometric thresholds, the evaluation considered the researcher’s awards and achievements within the discipline, further strengthening the validity of inclusion.
The D-index cutoff for recognizing top researchers varies in increments of 10, adjusted proportionally to the total number of scholars estimated for each discipline. This approach ensures that the ranking comprehensively incorporates the top 1% of leading mathematicians. Moreover, a proximity criterion was enforced whereby the difference between a scientist’s general H-index and their D-index must be 30% or less, reinforcing discipline-specific excellence.
Verification Practices
Recognizing the inherent limitations of raw bibliometric data, the analysts behind this ranking undertook rigorous manual verification of all scientist profiles. Each profile was cross-correlated against publications indexed in a broad spectrum of trustworthy sources to confirm consistency and mitigate errors.
While the number of publications in highly prestigious journals and conference proceedings is not a formal criterion influencing a researcher’s position in the Research.com ranking, it serves as a valuable secondary indicator of scientific contribution within Mathematics.
The final positioning is anchored on the D-index sourced from OpenAlex and CrossRef, which remain the most accessible and widely recognized bibliometric databases available to the research community at large.
