The first moment of primes in arithmetic progressions: beyond the Siegel–Walfisz range
We investigate the first moment of primes in progressions ∑q⩽x/N(q,a)=1ψ(x;q,a)−xφ(q)as x,N→∞. We show unconditionally that, when a=1, there is a significant bias towards negative values, uniformly for N⩽eclogx.

Squarefree Integers in Arithmetic Progressions to Smooth Moduli
Let $\varepsilon> 0$ be sufficiently small and let $0 < \eta < 1/522$ . We show that if X is large enough in terms of $\varepsilon $ , then for any squarefree integer $q \leq X^{196/261-\varepsilon }$ that is $X^{\eta ...

On the Restricted Divisor Function in Arithmetic Progressions [PDF]
We obtain several asymptotic estimates for the sums of the restricted divisor function τM,N (k) = #{1 6 m 6 M, 1 6 n 6 N : mn = k} over short arithmetic progressions, which improve some results of J. Truelsen.

THE LOGARITHMICALLY AVERAGED CHOWLA AND ELLIOTT CONJECTURES FOR TWO-POINT CORRELATIONS
Let $\unicode[STIX]{x1D706}$ denote the Liouville function. The Chowla conjecture, in the two-point correlation case, asserts that

We determine the order of magnitude of $\mathbb{E}|\sum _{n\leqslant x}f(n)|^{2q}$, where $f(n)$ is a Steinhaus or Rademacher random multiplicative function, and $0\leqslant q\leqslant 1$.

SECOND MOMENTS IN THE GENERALIZED GAUSS CIRCLE PROBLEM
The generalized Gauss circle problem concerns the lattice point discrepancy of large spheres. We study the Dirichlet series associated to $P_{k}(n)^{2}$, where $P_{k}(n)$ is the discrepancy between the volume of the $k$-dimensional sphere of radius ...

. We introduce the notion of cross-convolution of arithmetical functions as a special case of Narkiewicz’s regular convolution. We give asymptotic formulae for the summatory functions of certain generalized divisor-sum functions and Euler-type functions ...
