Decidability and classification of the theory of integers with primes

by Kaplan and Shelah. [KpSh:1082]

We show that under Dickson's conjecture about the distribution of primes in the natural numbers, the theory Th({Z},+,1,0, Pr) where Pr is a predicate for the prime numbers and their negations is decidable, unstable and supersimple. This is in contrast with Th({Z},+,0,Pr,<) which is known to be undecidable by the works of Jockusch, Bateman and Woods.
