Products in Residue Classes
John B. Friedlander, Par Kurlberg, Igor E. Shparlinski
We consider a problem of P. Erdos, A. M. Odlyzko and A. Sarkozy about the representation of residue classes modulo m by products of two not too large primes. While it seems that ev…

Integers without divisors from a fixed arithmetic progression
William D. Banks, John B. Friedlander, Florian Luca
Let a be an integer and q a prime number. In this paper, we find an asymptotic formula for the number of positive integers n < x with the property that no divisor d > 1 of n lies i…

Asymptotic sieve for primes
John Friedlander, Henryk Iwaniec
This article develops a new sieve method which by adding an additional axiom to the classical formulation breaks the well-known parity problem and allows one to detect primes in th…
