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 agenda
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.
