A Bombieri--Vinogradov Theorem with products of Gaussian primes as moduli

Abstract

We prove a version of the Bombieri--Vinogradov Theorem with certain products of Gaussian primes as moduli, making use of their special form as polynomial expressions in several variables. Adapting Vaughan's proof of the classical Bombieri--Vinogadov Theorem, cp. [10] to this setting, we apply the polynomial large sieve inequality that has been proved in [7] and which includes recent progress in Vinogradov's mean value theorem due to Parsell \emph{et al.} in [9]. From the benefit of these improvements, we obtain an extended range for the variables compared to the range obtained from standard arguments only.
