All bibliometric data utilized to calculate the citation-based metrics underpinning this ranking were collected on January 12, 2026. A researcher’s position within the ranking is determined exclusively by their D-index (Discipline H-index), a metric specifically designed to reflect the scholarly output and citation impact within the examined discipline—in this case, Mathematics. This focus ensures that the ranking measures domain-specific influence rather than general academic impact.
Scope of Research and Selection Criteria
Our analysis evaluated a vast pool of 279,971 scientist profiles aggregated from various bibliometric sources spanning all academic disciplines, identifying 61 scientists who specialize in Mathematics within Switzerland. To qualify for inclusion in this ranking, candidates were required to meet a minimum D-index threshold of 30, ensuring a high standard of scholarly excellence.
Additionally, a majority of each qualifying scientist’s top-tier publications needed to fall within the field of Mathematics, reflecting a genuine disciplinary focus. Awards and notable achievements in Mathematics were also considered as complementary indicators of research distinction.
The D-index cutoff values are calibrated in increments of 10 relative to the estimated total number of scholars per discipline, with the methodology guaranteeing representation of the top 1% of leading experts within each field. Moreover, to maintain alignment between general and discipline-specific impact, a proximity threshold of 30% or less between a scientist's general H-index and their D-index was mandated.
Verification Practices and Methodological Rigor
Recognizing the inherent limitations of raw bibliometric data, the research team conducted meticulous manual verification of all scientist profiles. Each profile was cross-referenced against publications listed in a diverse array of authoritative and trustworthy sources to ensure accuracy and integrity.
While the number of publications in prestigious journals and conference proceedings is not directly factored into the calculation of the D-index or position within the Research.com ranking, this metric serves as a valuable secondary signal of a researcher’s contribution to the specific scientific community.
The final ranking positions are derived from each researcher’s D-index based on data from OpenAlex and CrossRef, the leading and most respected citation and publication metadata repositories available to the scholarly community.
