离散缺项球平均数的新界

New bounds for discrete lacunary spherical averages

Theresa C. Anderson, Jose Madrid

摘要:

证明了对所有$p >\frac{d+1}{d-1}$,离散缺球极大函数在$l^p(\mathbb{Z}^d)$上有界.我们的范围是新的4维,在那里似乎很少有人知道一般的空隙半径。我们的技术遵循Kesler-Lacey-Mena的技术,使用Kloosterman细化来改善几个地方的估计,这导致了维度4的整体改善。

英文摘要:

We show that the discrete lacunary spherical maximal function is bounded on $l^p(\mathbb{Z}^d)$ for all $p >\frac{d+1}{d-1}$. Our range is new in dimension 4, where it appears that little was previously known for general lacunary radii. Our technique follows that of Kesler-Lacey-Mena, using the Kloosterman refinement to improve the estimates in several places, which leads to an overall improvement in dimension 4.
