On the exponent of distribution of the ternary divisor function

Number Theory 2019-02-20 v2

Abstract

We show that the exponent of distribution of the ternary divisor function d3d_3 in arithmetic progressions to prime moduli is at least 1/2+1/46, improving results of Heath-Brown and Friedlander--Iwaniec. Furthermore, when averaging over a fixed residue class, we prove that this exponent is increased to 1/2 +1/34.
