My Erdős Number

My Erdős number is 4.

I’ve co-authored with:

  • Daniel P. Friedman who co-authored with
  • Eugene E. Kohlbecker who co-authored with
  • Paul T. Bateman who co-authored with
  • Paul Erdős.


“Erdős” is spelled with “ő” not “ö”. It is with a double acute accent not an umlaut. (In LaTeX “\H{o}” not “\\\”o“.) Often, it is misspelled ”Erdös" for browser compatibility. See The Erdös Number Project.
