Data Sources and Citation Metrics
The 5th edition of the Research.com Best Mathematics Scientists in Cyprus Ranking is rooted in a robust and comprehensive data collection process. Primarily, the ranking leverages bibliometric data from OpenAlex and CrossRef, two of the most prominent and widely respected bibliometric databases accessible to the research community. Additionally, multiple other data sources have been utilized to enhance the breadth and depth of the dataset. The bibliometric data employed to devise the citation-based metrics were collected on January 12, 2026, ensuring the ranking reflects the most current and accurate scholarly information.
A scientist's position within the ranking is determined by their D-index (Discipline H-index), a discipline-specific variant of the traditional H-index. The D-index strictly evaluates papers and citations within the examined discipline, thereby providing a more accurate representation of a researcher’s impact in the field of Mathematics.
Scope of Research and Ranking Qualification Criteria
The scope of this ranking encompasses a detailed examination of 279,971 scientist profiles identified from a variety of bibliometric data sources spanning all disciplines. Specifically, within the Mathematics discipline, 4 scientists were carefully evaluated. To qualify for inclusion in the ranking, a scientist must have a D-index of at least 30, and a majority of their tier publications must be within the field of Mathematics.
Besides bibliometric metrics, scientists’ awards and achievements relevant to Mathematics have also been considered to provide a more holistic evaluation. The threshold for the D-index used to identify top researchers is calibrated in increments of 10 based on the estimated total number of active scholars in each discipline. This adaptive measure guarantees the inclusion of the top 1% of leading scholars. Furthermore, the ranking maintains a strict proximity quality check, requiring that the difference between a scientist’s general H-index and their Mathematics-specific D-index does not exceed 30%.
Additional Verification Practices
We acknowledge that raw bibliometric data alone cannot definitively evaluate the scholarly output of researchers. Therefore, all scientist profiles were subjected to meticulous manual verification and cross-correlation against publications indexed in a wide range of trustworthy and authoritative sources. While the number of papers published in leading journals and conference proceedings is not a direct factor in calculating a researcher’s rank, it provides a valuable secondary signal of their contribution to research in Mathematics.
The position in the ranking is ultimately established through the D-index values derived from information gathered from OpenAlex and CrossRef. These databases represent the most prominent and rigorously maintained bibliometric data repositories available, further supporting the credibility and reliability of the ranking.
