立方体骨架的极大算子

Maximal Operators for cube skeletons

Andrea Olivo, Pablo Shmerkin

摘要:

我们研究离散最大运营商平均(邻域)在平面上的平方,更一般地说,$k$ -骨架$\mathbb{R}^n$。虽然这些运营商是已知的,没有任何$L^p$上有界的,我们得到几乎尖锐的$L^p$界的每一个小的离散化规模。这些结果是T. Keleti,D. Nagy和P. Shmerkin以及R. Thornton,在包含缩放的$k$的集合上-单位立方体的sekeleton,中心在$\mathbb{R}^n$的每个点上。

英文摘要:

We study discretized maximal operators associated to averaging over (neighborhoods of) squares in the plane and, more generally, $k$-skeletons in $\mathbb{R}^n$. Although these operators are known not to be bounded on any $L^p$, we obtain nearly sharp $L^p$ bounds for every small discretization scale. These results are motivated by, and partially extend, recent results of T. Keleti, D. Nagy and P. Shmerkin, and of R. Thornton, on sets that contain a scaled $k$-sekeleton of the unit cube with center in every point of $\mathbb{R}^n$.
