Few small primes suffice to cover unit groups
Scott D. Hughes
Klurman, Shparlinski and Teräväinen showed that there is a set of at most primes of polylogarithmic size whose subset products cover the unit group $(\ma…

Effective logarithmic two-point Chowla bounds in every window
Scott D. Hughes
We quantify the entropy-decrement proof of the logarithmically averaged two-point Chowla theorem, uniformly in the affine forms and the averaging window. For L_i(n)=a_i n+b_i with…

Scott D. Hughes
For a positive integer , let denote the natural density of the set of for which is a sum of distinct divisors of . Erdős proved that exists, gave an unspe…

A Tsang-range high-moment bound for under GRH
Scott D. Hughes
Conditional on the Generalized Riemann Hypothesis for , we prove the Selberg--Tsang high-moment bound for at fixed squaref…
