当s > k > 3且n1,. . .,nk是大自然数,记为As,k(n)为系统xj 1 +的非负整数x的解的个数. . .+ xjs = nj(1 6 j 6 k).在n上适当的局部溶解度条件下,当s > k(k+1)时,得到了As,k(n)的一个渐近公式.这在凸性障碍处建立了希尔伯特-卡姆克问题的局部-全局原理。我们的论点涉及小弧估计超越平方根取消。
When s > k > 3 and n1, . . . , nk are large natural numbers, denote by As,k(n) the number of solutions in non-negative integers x to the system x j 1 + . . .+ xjs = nj (1 6 j 6 k). Under appropriate local solubility conditions on n, we obtain an asymptotic formula for As,k(n) when s > k(k+1). This establishes a local-global principle in the Hilbert-Kamke problem at the convexity barrier. Our arguments involve minor arc estimates going beyond square-root cancellation.
