Carl Pomerance.

Carl Pomerance is one of the top number theorists of his time. He received his PhD from Harvard University in 1972 for his study that any odd perfect number N has at least 7 distinct prime factors and immediately joined the faculty at the University of Georgia, becoming full professor in 1982. He subsequently worked at Lucent Technologies for a number of years, and then became a Distinguished Professor at Dartmouth College.

Harvard University campus (old map) Harvard University (incorporated as The President and Fellows of Harvard College) is an accredited private university in Cambridge, Massachusetts. ... In mathematics, a perfect number is defined as an integer which is the sum of its proper positive divisors, excluding itself. ... In number theory, the prime factors of a positive integer are the prime numbers that divide into that integer exactly, without leaving a remainder. ... The University of Georgia, is located approximately 70 miles north-east of Atlanta in Athens, Georgia and is the largest institution of higher learning and research in the State of Georgia. ...

He has won many teaching and research awards, including the Chauvenet Prize in 1985, MAA's distinguished university teaching award in 1997, and the Conant Prize in 2001. He has over 120 publications to his credit, including co-authorship with R. Crandall of Prime numbers: a computational perspective, Springer-Verlag, 2001. He is the inventor of one of the most important factorisation methods, the quadratic sieve algorithm, which was used in 1994 for the factorisation of RSA-129. The Chauvenet Prize, consisting of a prize of $1,000 and a certificate, is awarded yearly by the Mathematical Association of America in recognition of an outstanding expository article on a mathematical topic. ... Springer Science+Business Media or Springer (IPA: ) is a worldwide publishing company based in Germany which focuses on academic journals and books in the fields of science, technology and medicine. ... In number theory, the integer factorization problem is the problem of finding a non-trivial divisor of a composite number; for example, given a number like 91, the challenge is to find a number such as 7 which divides it. ... The quadratic sieve algorithm (QS) is a modern integer factorization algorithm and, in practice, the second fastest method known (after the general number field sieve). ... In mathematics, RSA-129 is one of the RSA numbers, large semiprimes that are part of the RSA Factoring Challenge. ...

His Erdős number is 1. The ErdÅ‘s number, honouring the late Hungarian mathematician Paul ErdÅ‘s, one of the most prolific writers of mathematical papers, is a way of describing the collaborative distance, in regard to mathematical papers, between an author and ErdÅ‘s. ...
