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 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.
