My Erdős Number
What is an Erdős Number? It is the number of "hops" needed
to connect the author of a paper with the prolific late mathematician
Paul Erdős. An author's Erdős number is 1 if they have coauthored a
paper with Erdős, it is 2 if they have not coauthored with
Erdős, but they have coauthored a paper with someone who has
coauthored a paper with Erdős, etc. To learn more about
Erdős numbers, check out the Erdős Number Project.
