Sums of three cubes, II

Number Theory 2023-06-01 v1

Abstract

Estimates are provided for ssth moments of cubic smooth Weyl sums, when 4s84\le s\le 8, by enhancing the author's iterative method that delivers estimates beyond classical convexity. As a consequence, an improved lower bound is presented for the number of integers not exceeding XX that are represented as the sum of three cubes of natural numbers.
