摘要
我们提供了小弧上光滑Weyl和的新估计,并探讨了它们对α n k的分数部分分布的影响$\alpha n^k$。特别是,当k小于6 $k\geqslant 6$和ρ (k) $\rho (k)$通过关系ρ定义时(k)−1 = k (log k + 8.02113)$\rho (k)^{-1}=k(\log k+8.02113)$,那么对于所有的大数N $N$,有一个整数N $n$, 1≤N≤N $1\leqslant n\leqslant N$∥α n k∥n−ρ (k)$\Vert \alpha n^k\Vert \leqslant N^{-\rho (k)}$。
We provide new estimates for smooth Weyl sums on minor arcs and explore their consequences for the distribution of the fractional parts of . In particular, when and is defined via the relation , then for all large numbers there is an integer with for which .
