Abstract

Goldston, Pintz and Y\i ld\i r\i m have shown that if the primes have `level of distribution' θ\theta for some θ>1/2\theta>1/2 then there exists a constant C(θ)C(\theta), such that there are infinitely many integers nn for which the interval [n,n+C(θ)][n,n+C(\theta)] contains two primes. We show under the same assumption that for any integer k1k\ge 1 there exists constants D(θ,k)D(\theta,k) and r(θ,k)r(\theta,k), such that there are infinitely many integers nn for which the interval [n,n+D(θ,k)][n,n+D(\theta,k)] contains two primes and kk almost-primes, with all of the almost-primes having at most r(θ,k)r(\theta,k) prime factors. If θ\theta can be taken as large as 1ϵ1-\epsilon, and provided that numbers with 2, 3, or 4 prime factors also have level of distribution 1ϵ1-\epsilon, we show that there are infinitely many integers nn such that the interval [n,n+90][n,n+90] contains 2 primes and a number with at most 4 prime factors.
