The 2nd edition of Research.com ranking of the best scientists in the
field of Mathematics was created using data
combined from multiple 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 publications and citation
data for an examined discipline.

The focus of our Mathematics research
Our best scholars ranking is a credible
list of leading scientists from the discipline of
Mathematics, created using a detailed
analysis of 166,880 scholars identified
from multiple bibliometric data sources. For the discipline of
Mathematics, over 6262 scientists were
investigated.
What is D-index inclusion threshold for Mathematics
The D-index threshold for including a researcher to be
evaluated is placed at 30 if
most of their publications are in the area of Mathematics. The
approval criteria for researchers to be
considered into the ranking of top scientists are based on the D-index, ratio
of the publications made within the given discipline
as well as the awards and achievements of the scholars. The
D-index threshold for listing leading scholars is
set as an increment of 10 depending on the overall number of scholars
projected for each area od study whilst
making sure that the top 1% of leading scholars are
incorporated into the list. We expect a proximity of
30% or less between a scholar’s general H-index and their D-index.
Additional verification practices
As our primary aim is to ensure that only
actual scholars are included in
the ranking we realize that raw data are never
supposed to be a complete measure to assess the
output of researchers. This is why
we manually inspect every profile and cross-correlate it against publications in a
wide range of trustworthy sources. Even though it’s not a
element contributing to a scholar’s position in
our ranking, the amount of papers published in
well-known journals and conference proceedings should be a
reliable secondary implication of their contribution to research in a
selected field of study. Position in the ranking is
determined by each researcher’s D-index
using metrics compiled from OpenAlex and
CrossRef, which are the most prominent and well-known bibliometric
databases of this type available to the research community. A
thorough explanation of our research policy
can be found on our
methodology page.
Our mission
Our mission is to inspire scholars,
entrepreneurs and administrative bodies
around the world to investigate where top experts are heading
and to offer a way for the entire scientific community to
get to know who the leading experts in specific
fields of research, in different countries, or even within research
institutions are.
