The 2nd edition of Research.com ranking of the best scientists in the
discipline of Mathematics was created using data
consolidated from a wide range of data sources including OpenAlex and
CrossRef. The bibliometric data for estimating the citation-based metrics were
collected on 21-12-2022. Position in the ranking is based on a
researcher’s D-index (Discipline H-index), which
only includes publications and citation
values for an examined discipline.
The scope of our Mathematics research
Research.com’s best researchers ranking is a trustworthy account of leading researchers from the field of Mathematics, based on a meticulous study of 166,880 scientists discovered from a variety of bibliometric data sources. For the field of Mathematics, over 6262 researchers were examined.
What is D-index inclusion threshold for Mathematics
The D-index threshold for accepting a scholar to be examined is set to 30 if most of their publications are in the field of Mathematics. The acceptance requirements for scholars to be considered into the ranking of top researchers are based on the D-index, ratio of the contributions made within the given area plus the awards and achievements of the scientists. The D-index threshold for considering best scientists is set as an increment of 10 depending on the total number of scientists estimated for each area od study whilst ensuring that the top 1% of leading scientists are considered into the ranking. We estimate a proximity of 30% or less between a scientist’s general H-index and their D-index.
Extra verification practices
Because our primary mission is to make sure that only actual researchers are listed in Research.com ranking we are aware that raw data are never supposed to be an absolute tool to assess the output of researchers. For that reason we manually inspect each profile and cross-correlate it against publications in a varied range of trustworthy sources. Even though it’s not a element defining a scientist’s position in our ranking, the number of documents published in well-known journals and conference proceedings should be a reliable secondary signal of their contribution to research in a specific field of study. Position in the ranking is established using each scholar’s D-index with the help of metrics compiled from OpenAlex and CrossRef, which are the most credible and well-known bibliometric databases of this kind accessible to the research community. A comprehensive overview of our research process can be found on our methodology page.
Our aim is to motivate scholars, entrepreneurs and decision-makers around the world to explore where top experts are heading and to provide a way for the whole research community to discover who the leading experts in specific areas of study, in various countries, or even within research institutions are.
