离散分数次积分算子与Weyl和的均值

On discrete fractional integral operators and mean values of Weyl Sums

Lillian B. Pierce

摘要:

在本文中,我们证明了新的$(\ell^p, \ell^q)$界的离散分数次积分运营商的应用技术的启发圆的方法Hardy和Littlewood的傅立叶乘子。从不同的角度来看,我们描述明确的傅立叶乘数和Weyl和的平均值之间的相互作用。这些平均值将正整数$l$的表示的数量$r_{s,k}(l)$的平均行为表示为$s$的正$k$的幂之和。最近的深入成果的背景下,华林的问题和外尔和使我们能够证明进一步范围内的互补结果的离散运营商正在考虑。

英文摘要:

In this paper we prove new $(\ell^p, \ell^q)$ bounds for a discrete fractional integral operator by applying techniques motivated by the circle method of Hardy and Littlewood to the Fourier multiplier of the operator. From a different perspective, we describe explicit interactions between the Fourier multiplier and mean values of Weyl sums. These mean values express the average behaviour of the number $r_{s,k}(l)$ of representations of a positive integer $l$ as a sum of $s$ positive $k$-th powers. Recent deep results within the context of Waring's problem and Weyl sums enable us to prove a further range of complementary results for the discrete operator under consideration.
