Lower bounds on expressions depending on the functions {\boldmath $φ (n)$ }, {\boldmath $ψ (n)$ } and {\boldmath $σ (n)$ }, III

S. I. Dimitrov

This work is concerned with the study of lower bounds for various expressions related to the arithmetic functions $φ (n)$ , $ψ (n)$ and $σ (n)$ . Several explicit estimates are establis…

Barban-Davenport-Halberstam type theorems for exponential sums and Piatetski-Shapiro primes

S. I. Dimitrov

In this paper we establish three Barban-Davenport-Halberstam type theorems. Namely for exponential sums over primes, for Piatetski-Shapiro primes and for exponential sums over Piat…

The Bombieri-Vinogradov theorem for primes of the form $p = x^{2} + y^{2} + 1$

S. I. Dimitrov

In this paper, we establish a Bombieri-Vinogradov type result for prime numbers of the form $p = x^{2} + y^{2} + 1$ . The proof is based on the enveloping sieve.
