我们提供的双二次光滑外尔和的s矩估计,当10 6 6 12,通过增强第二作者的迭代方法,提供超越经典凸性障碍的估计。因此,所有满足n r(mod 16)且1 6 r 6 12的足够大的整数n都可以写成12个光滑数的双二次方之和。
We provide estimates for s moments of biquadratic smooth Weyl sums, when 10 6 s 6 12, by enhancing the second author’s iterative method that delivers estimates beyond the classical convexity barrier. As a consequence, all sufficiently large integers n satisfying n ≡ r (mod 16), with 1 6 r 6 12, can be written as a sum of 12 biquadrates of smooth numbers.
