Data Sources and Citation Metrics
The 5th edition of the Research.com Best Mathematics Scientists in Vietnam Ranking is based primarily on comprehensive bibliometric data collected from OpenAlex and CrossRef, supplemented by multiple other authoritative data sources. These databases form the foundation for the citation-based metrics employed in the ranking. The bibliometric data utilized for this edition were harvested on January 12, 2026, ensuring recency and relevance. A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a metric that considers only those publications and citation counts strictly within the examined discipline—in this case, Mathematics—thereby offering a precise reflection of a researcher’s scholarly impact in their specialized field.
Scope of Research Considered
The ranking assessed a total of 279,971 scientist profiles identified from a diverse array of bibliometric data repositories spanning all scientific disciplines. Within this extensive dataset, 2,312 profiles were specifically categorized under Mathematics. To qualify for inclusion in the Mathematics ranking, a scientist’s D-index needed to be at least 30, with the majority of their tier publications clearly situated in the Mathematics domain. Additionally, recognition of a scientist’s awards and achievements within Mathematics factored into the evaluation. The threshold for the D-index is dynamically adjusted in increments of 10 according to the approximate number of active scholars in each discipline, while ensuring that the top 1% of leading researchers are consistently included. Importantly, candidates were required to exhibit a proximity of no more than 30% between their general H-index and their discipline-specific D-index, ensuring genuine specialization and impact within Mathematics.
Additional Verification and Methodological Rigor
Recognizing that raw bibliometric data cannot serve as an absolute measure of scholarly performance, the Research.com team undertook thorough manual verification of all candidate profiles. This manual curation process involved cross-correlating each scientist’s publication record against a wide range of trustworthy academic sources to substantiate the accuracy and relevance of their contributions. Although the number of papers published in prominent journals and major conference proceedings does not directly affect a researcher’s ranking position, it is regarded as a valuable secondary indicator of scientific influence within the field.
The ranking position itself is firmly grounded on the D-index derived from citation and publication metadata sourced primarily from OpenAlex and CrossRef—two of the most highly regarded bibliometric databases available to the global research community.
