The 2nd edition of Research.com ranking of the best researchers in the
discipline of Mathematics is based on data
derived from a wide range of data sources including OpenAlex and
CrossRef. The bibliometric data for evaluating 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 papers and citation
data for an examined discipline.

The range of our Mathematics research
Research.com’s best researchers ranking is a credible
account of leading researchers from the discipline of
Mathematics, created using a detailed
study of 166,880 scientists discovered
from multiple bibliometric data sources. For the area of
Mathematics, more than 6262 scientists were
analysed.
What is D-index inclusion threshold for Mathematics
The D-index threshold for approving a scientist to be
evaluated is placed at 30 if
the majority of of their publications are in the discipline of Mathematics. The
approval factors for scientists to be
considered into the ranking of top scholars are based on the D-index, ratio
of the publications made within the specific field of study
in addition to the awards and achievements of the scientists. The
D-index threshold for considering leading scholars is
set as an increment of 10 depending on the total number of scientists
estimated for each area od study whilst
making sure that the top 1% of best scientists are
incorporated into the ranking. We estimate a proximity of
30% or less between a scientist’s general H-index and their D-index.
Other verification practices
As our main aim is to guarantee that only
actual scholars are included in
our ranking we are aware that raw data are never
supposed to be a full tool to evaluate the
output of scientists. For that reason
we manually check each profile and cross-correlate it against publications in a
wide range of trustworthy sources. While it’s not a
factor impacting a scientist’s position in
Research.com ranking, the amount of papers published in
major journals and conference proceedings should form a
credible secondary indication of their contribution to research in a
given area of science. Position in the ranking is
based on each scientist’s D-index
with the help of metrics compiled from OpenAlex and
CrossRef, which are the most credible and well-established bibliometric
databases of this type accessible to the research community. A
comprehensive overview of our research process
can be found on our
methodology page.
Our goal
Our goal is to inspire scholars,
companies and administrative bodies
around the world to investigate where prominent experts are heading
and to provide an opportunity for the entire scientific community to
discover who the leading experts in specific
disciplines, in various countries, or even within research
institutions are.
