There is a long history of interest in primes of a special form. Writing for a prime and for the next larger prime, some of the famous examples are: twin primes (), primes represented by polynomials (the simplest case is ), Sophie Germaine primes ( is prime), and many others.
None of these problems has been connected to the zeros of the Riemann -function is a satisfactory way. Turan [38 #127] related twin primes to zeros of -functions near , and it is possible that recent ideas on the distribution of low-lying zeros in a family will shed some light on that problem. Bogolmony and Keating [Nonlinearity 8, 1115-1131] [Nonlinearity 9, 911-935] derive all -correlation functions by assuming the Hardy-Littlewood conjectures and ignoring error terms, However, one cannot deduce the Hardy-Littlewood conjectures from the correlation functions.
Problem: Devise a believable conjecture about the zeros of one or more -functions which implies that there are infinitely many primes of one of the special forms described above.
