The 2nd edition of Research.com ranking of the best scholars in the
field of Mathematics relies os data
combined from various data sources including OpenAlex and
CrossRef. The bibliometric data for evaluating the citation-based metrics were
gathered on 21-12-2022. Position in the ranking is based on a scholar’s
D-index (Discipline H-index), which only includes
publications and citation values for an examined discipline.
The scope of our Mathematics research
Our best scholars ranking is a trustworthy account of leading scholars from the field of Mathematics, created using a thorough examination of 166,880 scientists discovered from multiple bibliometric data sources. For the field of Mathematics, more than 6262 researchers were investigated.
What is D-index inclusion threshold for Mathematics
The D-index threshold for accepting a scholar to be considered is established at 30 if most of their publications are in the discipline of Mathematics. The acceptance factors for scientists to be considered into the ranking of top scientists are based on the D-index, ratio of the contributions made within the selected area as well as the awards and achievements of the scholars. The D-index threshold for considering leading researchers is set as an increment of 10 depending on the overall number of scholars assessed for each discipline whilst guaranteeing that the top 1% of leading scholars are incorporated into the list. We estimate a proximity of 30% or less between a scholar’s general H-index and their D-index.
Extra verification rules
As our primary goal is to ensure that only genuine scientists are listed in Research.com ranking we are aware that raw data are never meant to be an absolute tool to assess the contributions of scholars. Because of that we manually verify every profile and cross-correlate it against publications in a varied range of credible sources. Although it’s not a metric impacting a researcher’s position in our ranking, the quantity of papers published in well-known journals and conference proceedings should constitute a reliable secondary implication of their contribution to research in a specific discipline. Position in the ranking is established using each scientist’s D-index using data compiled from OpenAlex and CrossRef, which are the most prominent and well-established bibliometric databases of this kind open to the research community. A thorough overview of our research process can be found on our methodology page.
Our objective is to motivate researchers, entrepreneurs and decision-makers worldwide to examine where prominent experts are heading and to give an opportunity for the entire scientific community to get to know who the leading experts in specific areas of study, in different countries, or even within research institutions are.
