The 2nd edition of Research.com ranking of the best scientists in the
field of Mathematics is based on data
combined from various 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
scholar’s D-index (Discipline H-index), which
only includes publications and citation
values for an examined discipline.
The focus of our Mathematics research
Our best scientists ranking is a trustworthy list of leading scientists from the discipline of Mathematics, based on a detailed study of 166,880 scholars determined from multiple bibliometric data sources. For the field of Mathematics, over 6262 scholars were examined.
What is D-index inclusion threshold for Mathematics
The D-index threshold for accepting a scientist to be considered is placed at 30 if the majority of of their publications are in the field of Mathematics. The inclusion requirements for scientists to be considered into the ranking of top scientists are based on the D-index, proportion of the contributions made within the given field of study in addition to the awards and achievements of the scholars. The D-index threshold for considering leading scientists is set as an increment of 10 depending on the total number of scientists projected for each scientific field whilst ensuring that the top 1% of leading scientists are added into the ranking. We expect a proximity of 30% or less between a scholar’s general H-index and their D-index.
Additional verification methods
As our primary goal is to make sure that only credible scientists are listed in the ranking we believe that metrics are never meant to be a complete means to evaluate the work of researchers. Because of that we manually verify each profile and cross-correlate it against publications in a wide range of reliable sources. Although it’s not a metric impacting a researcher’s position in the ranking, the amount of papers published in prominent journals and conference proceedings should constitute a reliable secondary implication of their contribution to research in a specific field of study. Position in the ranking is determined by each scientist’s D-index according to data compiled from OpenAlex and CrossRef, which are the most trustworthy and well-known bibliometric databases of this type accessible to the scientific community. A thorough definition of our research policy can be found on our methodology page.
Our aim is to inspire scientists, businessmen and decision-makers worldwide to examine where top experts are heading and to provide an opportunity for the whole scientific community to get to know who the leading experts in specific fields of research, in various countries, or even within research institutions are.
