A mean value theorem of Bombieri's type
In this paper we establish the distribution of prime numbers in a given arithmetic progression for which is squarefree.
Let Γ ⊂ ℚ * be a finitely generated subgroup and let p be a prime such that the reduction group Γₚ is a well defined subgroup of the multiplicative group ₚ*. We prove an asymptotic formula for the average of the number of primes p ≤ x for which [ₚ*:Γₚ] = m. The average is taken over all finitely generated subgroups , with and , with a range of uniformity for every i = 1,...,r. We also prove an asymptotic formula for the mean square of the error terms in the asymptotic formula with a similar...
In this article we study, using elementary and combinatorial methods, the distribution of quadratic non-residues which are not primitive roots modulo or for an odd prime and an integer.
