Curtis Niles Cooper is an American mathematician who was a professor at the University of Central Missouri, in the Department of Mathematics and Computer Science.
GIMPS
Using software from the
Cooper and Boone became the first GIMPS contributors to find two primes when they also found the 44th known Mersenne prime, 232,582,657 − 1 (or M32,582,657), which has 9,808,358 digits . This prime was discovered on September 4, 2006 using a PC cluster of over 850 machines. This is the tenth Mersenne prime for GIMPS.[2]
On January 25, 2013, Cooper found his third Mersenne prime of 257,885,161 − 1.[3]
On September 17, 2015, Cooper's computer reported yet another Mersenne prime, 274,207,281 - 1, which was the largest known prime number at 22,338,618 decimal digits. The report was, however, unnoticed until January 7, 2016.[4]
Areas of research
Cooper's own work has mainly been in elementary
Cooper is also the editor of the publication Fibonacci Quarterly.
