In this paper we improve the best known to date result of Dress-Iwaniec-Tenenbaum, getting (log x)^2 instead of (log x)^(5/2). We use a weighted form of Vaughan's identity, allowing a smooth truncation inside the procedure, and an estimate due to Barban-Vehov and Graham related to Selberg's sieve. We give effective and non-effective versions of the result. 
Optimality for the two-parameter quadratic sieve
We study the two-parameter quadratic sieve for a general test function. We prove, under some very general assumptions, that the function considered by Barban and Vehov [BV68] and Graham [Gra78] for

We follow a paper by Sedunova regarding Vaughan’s basic mean value Theorem to improve and complete a more general demonstration for a suitable class of arithmetic functions as started by Cojocaru and

A variant of Bombieri-Vinogradov theorem with explicit constants
In this paper we improve the result of Akbary and Hambrook by a factor of log x by obtaining a better version of Vaughan's inequality and using the explicit variant of an inequality connected to the

— In this paper we improve the result of [1] with getting (log x) 2 instead of (log x) 2 . In particular we obtain a better version of Vaughan’s inequality by applying the explicit variant of an
A variant of the Bombieri-Vinogradov theorem with explicit constants and applications
We give an effective version with explicit constants of a mean value theorem of Vaughan related to the values of ψ(y, χ), the twisted summatory function associated to the von Mangoldt function Λ and
A generalization of the Pólya–Vinogradov inequality
In this paper we consider an approach of Dobrowolski and Williams which leads to a generalization of the Pólya–Vinogradov inequality. We show how the Dobrowolski–Williams approach is related to the
The analytic principle of the large sieve
E. Bombieri [12] has written at length concerning applications of the large sieve to number theory. Our intent here is to complement his exposition by devoting our attention to the analytic principle

The ternary Goldbach problem
The ternary Goldbach conjecture, or three-primes problem, states that every odd number n greater than 5 can be written as the sum of three primes. The conjecture, posed in 1742, remained unsolved
An effective Bombieri–Vinogradov theorem and its applications
We use suitably Page’s theorem to get effective results for interesting problems, by avoiding the ineffective Siegel’s theorem.
