The Erdös Number Project
| The Erdös Number Project |
This is the website for the Erdös Number Project, which studies research collaboration among mathematicians. For reasons beyond our control, this site may soon disappear from this location. However, a new version exists. Please click here to visit the new Erdös Number Project website and bookmark it for future reference. Updates will be made primarily to the new site.

WHAT’S INSIDE:
- Information about the Erdös Number Project: General overview, including our (admittedly arbitrary) rules for what counts as a research collaboration.
- The Erdös Number Project Data Files: Lists of all of Paul Erdös’s coauthors and their respective coauthors, organized in various ways. There are also links to websites of or about Erdös’s coauthors.
- Facts about Erdös Numbers and the Collaboration Graph: Statistical descriptions of Erdös number data, a file of the sub graph induced by Erdös coauthors, Erdös number record holders, facts about collaboration in mathematical research and the collaboration graph, including some information about publishing habits of mathematicians (for example, the median number of papers is 2, and the mean is about 7). This subpage has loads of information about the collaboration graph and Erdös numbers, including the distribution of Erdös numbers (they range up to 13, but the average is less than 5, and almost everyone with a finite Erdös number has a number less than 8) and “Erdös numbers of the second kind”.
- Some Famous People with Finite Erdös Numbers: Fields Medalists and Nobel Prize winners have small Erdös numbers.
- Computing Your Erdös Number: It may be smaller than you think.
- Research on Collaboration in Research: Papers on collaboration in scientific research, collaboration graphs and other small world graphs, and Erdös numbers. A lot of research is currently being done by various scientists on collaboration graphs and related topics.
- Information about Paul Erdös (1913–1996): Information about and links to books, films, articles, memorials, reminiscences.
- Publications of Paul Erdös: They continued to appear more than ten years after his death.
- Items of Interest Related to Erdös Numbers: Six degrees of separation, the Kevin Bacon game, Small Worlds, academic genealogy, Hank Aaron, graph theory, and other miscellany.
I have finished updating all the coauthor lists, and I am slowly putting the new information onto this site. The data are based primarily on all items appearing in MathSciNet and DBLP through mid-2020. About 2600 new people with Erdös number 2 are being added.
