Cem Yalçın Yıldırım (born 8 July 1961) [1] is a Turkish mathematician who specializes in number theory.
Yıldırım obtained his B.Sc from Middle East Technical University in Ankara, Turkey and his PhD from the University of Toronto in 1990. [2] His advisor was John Friedlander. He is currently a faculty member at Boğaziçi University in Istanbul, Turkey.
In 2009, Dan Goldston, János Pintz, and Yıldırım proved that for any positive number ε there exist primes p and p′ such that the difference between p and p′ is smaller than ε log p. [3] This result was originally reported in 2003 by Goldston and Yıldırım but was later retracted. [4] [5] Then Janos Pintz joined the team and they completed the proof in 2005 and developed the so called GPY sieve.
