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 devising 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
includes exclusively papers and citation
values for an examined discipline.

The scope of our Mathematics research
Research.com’s best researchers ranking is a reliable
account of leading scholars from the field of
Mathematics, established by means of a meticulous
examination of 166,880 scientists discovered
from a variety of bibliometric data sources. For the field of
Mathematics, more than 6262 scholars were
investigated.
What is D-index approval threshold for Mathematics
The D-index threshold for approving a scientist to be
examined is placed at 30 if
most of their publications are in the discipline of Mathematics. The
approval factors for scholars to be
considered into the ranking of top scholars are based on the D-index, proportion
of the publications made within the specific discipline
in addition to the awards and achievements of the researchers. The
D-index threshold for considering leading researchers is
set as an increment of 10 depending on the overall number of scientists
estimated for each scientific field whilst
guaranteeing that the top 1% of best scientists are
added into the ranking. We expect a proximity of
30% or less between a scientist’s general H-index and their D-index.
Additional verification methods
Because our main mission is to make sure that only
genuine scientists are mentioned in
our ranking we believe that numbers are never
supposed to be a full measure to assess the
output of scientists. Because of that
we manually inspect every profile and cross-correlate it against publications in a
wide range of reliable sources. While it’s not a
factor impacting a researcher’s position in
Research.com ranking, the quantity of papers published in
well-known journals and conference proceedings should form a
valuable secondary signal of their contribution to research in a
selected area of science. Position in the ranking is
established using each researcher’s D-index
with the help of information gathered from OpenAlex and
CrossRef, which are the most credible and well-established bibliometric
databases of this kind open to the scientific community. A
comprehensive explanation of our research policy
can be found on our
methodology page.
Our goal
Our objective is to motivate scholars,
companies and administrative bodies
around the world to explore where leading experts are heading
and to give an opportunity for the entire research community to
find out who the leading experts in specific
areas of study, in various countries, or even within research
institutions are.
