A researcher’s position within the ranking is determined by their D-index (Discipline H-index), a specialized metric that considers only publications and citation counts relevant to the discipline under examination—in this case, Mathematics. This ensures that the ranking accurately reflects a scientist’s scholarly impact specifically within their field.
Scope of Research and Selection Criteria
The ranking scope was defined by an initial examination of 279,971 scientist profiles identified from diverse bibliometric data sources across all academic disciplines. Within this dataset, 5 scientists specializing in Mathematics based in Ireland were rigorously evaluated.
To qualify for inclusion, a scientist’s D-index had to be at least 30, with the majority of their tier publications concentrated in Mathematics. Additionally, a scientist’s distinguished awards and achievements within the mathematical sciences were also factored into the evaluation process. The D-index threshold for top researchers is adapted in increments of 10 relative to the estimated total number of scholars per discipline, ensuring that the ranking reliably captures the top 1% of leading scholars.
Moreover, to maintain disciplinary focus, a proximity threshold was applied wherein the discrepancy between a scientist’s overall H-index and their D-index must be 30% or less. This criterion ensures the researchers included are not only prolific but also demonstrate consistent impact within Mathematics specifically.
Additional Verification Practices
Recognizing that raw bibliometric data alone cannot serve as an absolute measure of scholarly output, the Research.com team implemented thorough manual verification procedures. Each scientist’s profile was carefully cross-checked against publications indexed in a broad spectrum of reputable sources to confirm accuracy and relevance.
While the number of papers published in high-impact journals and respected conference proceedings does not directly affect a researcher’s ranking position, it is viewed as a valuable secondary indicator of scholarly contribution and influence within the field.
The ranking itself is driven by each researcher’s D-index, derived principally from the trusted bibliometric repositories OpenAlex and CrossRef, currently considered among the most prominent and reliable databases accessible to the global research community.
