Paul Erdős and Egyptian Fractions

  • Ronald L. Graham
Part of the Bolyai Society Mathematical Studies book series (BSMS, volume 25)


One of Paul Erdős’ earliest mathematical interests was the study of so-called Egyptian fractions, that is, finite sums of distinct fractions having numerator 1. In this note we survey various results in this subject, many of which were motivated by Erdős’ problems and conjectures on such sums. This note complements the excellent treatment of this topic given by A. Schinzel in 2002.1
