A researcher’s position in this ranking is determined by their D-index (Discipline H-index), a refined bibliometric indicator that includes only publications and citation metrics relevant to the specific discipline under examination, in this case, Mathematics. This discipline-specific methodology allows a more precise evaluation of scholarly impact within the designated field.
Scope of Research and Inclusion Criteria
The ranking process began with the examination of 279,971 scientist profiles aggregated from diverse bibliometric sources across all scholarly disciplines. From this vast dataset, 87 scientists specializing in Mathematics in Spain were identified for detailed consideration.
To qualify for inclusion in this ranking, a scientist must meet two primary criteria:
- Possess a D-index of at least 30.
- Have a majority of their tier publications focused specifically on Mathematics.
In addition to bibliometric thresholds, the researchers’ awards and achievements within the Mathematics community were also carefully assessed to provide context beyond pure citation metrics.
The threshold for the D-index is dynamically adjusted in increments of 10 based on the estimated population of scholars in each discipline, ensuring the top 1% of leading researchers are consistently represented. Furthermore, a criterion requiring the proximity between a scientist’s overall H-index and their Mathematics-specific D-index to be within 30% ensures that the profile reflects significant disciplinary focus and impact.
Additional Verification Practices
Recognizing the limitations inherent in raw bibliometric data as an absolute measure of scholarly output, the Research.com team undertook extensive manual verification of all scientist profiles. Each profile was cross-correlated with publications recorded in a broad array of trustworthy and reputable sources to validate the accuracy and relevance of the data.
While the number of publications in renowned journals and conference proceedings does not directly influence a researcher’s ranking position, it serves as a valuable secondary indicator of contribution and prominence within the Mathematics research community.
The ranking positions are ultimately established by the D-index calculated from data gathered via OpenAlex and CrossRef, two of the most prominent and widely respected bibliometric databases available to the research community today.
