Let A, ɛ > 0 be arbitrary. Suppose that x is a sufficiently large positive number. In this paper we prove that the number of integers n ∈ ( x, x + H ], satisfying some natural conditions, which cannot be represented as the sum of five cubes of pri

We prove two average results on the distribution of primes in arithmetic progressions to widely separated moduli, one of which improves upon Elliott’s work [2].

In 1923 G. H. Hardy and J. E. Littlewood [3] conjectured that every large integer, not being a square, may be expressed as the sum of a prime and a square. Let v(n) be the number of representationf of an integer n in this manner. ...

Let u amd a be coprime positive integers. Put, for a non-zero integer k, ψ(x; q, a, 2k)=Σ Λ(m)Λ(n) where Λ is the von Mangoldt function. It is expected that, provided (a+2k, q)=1, ...

Let π(x; q, a)denote the number of primes not exceeding x and being congruent to a modulo q. In 1936 P. Turan [6] showed that, under the extended Riemann hypothesis, ...

for any fixed non-zero integer a and almost-all moduli q with {q, a)=l. His argument based upon the weighted linear sieve and the Brun-Titchmarsh theorem on average, which are due to H. E. Richert [10] and C. Hooley [4], respectively. H. Iwaniec's fu

with some absolute constant L, vide [16, Kap. X]. Many works have been done to obtain an explicit value of this Linnik constant. The best known result is L = 5.5 due to D. R. Heath-Brown [14]. The Bombieri-Vinogradov theorem, see [7,§28], has the sa

with a wide uniformity in real a, where A is the von Mangoldt function and, for real 6, e{6) = exp(2niO). By using a combinatrial identity, R. C. Vaughan presented an elegant simple argument on it, see [2], for instance. J.-r.Chen's theorem on the bi
