Daniel Goldston

From Wikipedia, the free encyclopedia

Daniel Alan Goldston (born January 4, 1954 in Oakland, California) is an American mathematician who specializes in number theory. He is currently a professor of mathematics at San Jose State University.

Goldston is best known for the following result that he, János Pintz, and Cem Yildirim proved in 2005 [1]:

\liminf_{n\to\infty}\frac{p_{n+1}-p_n}{\log p_n}=0

where p_n\ denotes the nth prime number. In other words, for every c>0\ , there exist infinitely many pairs of consecutive primes p_n\ and p_{n+1}\ which are closer to each other than the average distance between consecutive primes by a factor of c\ , i.e., p_{n+1}-p_n<c\log p_n\ .

In fact, if they assume the Elliott-Halberstam conjecture, then they can also show that primes within 16 of each other occur infinitely often, which is nearly the twin prime conjecture.
