关于自共形集上收缩目标集的Hausdorff测度

On the Hausdorff measure of shrinking target sets on self-conformal sets

Demi Allen, Balázs Bárány

摘要:

本文研究了自共形集上收缩目标集的Hausdorff测度。我们在这里感兴趣的集合的豪斯多夫维数是由Hill和Velani在1995年建立的。然而,直到最近,人们对这些特定集合的豪斯多夫测度知之甚少。在本文中,我们提供了一个完整的表征的Hausdorff措施,这些集,获得一个二分法的Hausdorff措施,这是由收敛或发散的总和取决于我们的“收缩目标”的半径。我们的主要结果补充了Levesley,Salp和Velani~(2007)的早期工作以及Baker(2019)的近期工作。

英文摘要:

In this article, we study the Hausdorff measure of shrinking target sets on self-conformal sets. The Hausdorff dimension of the sets we are interested in here was established by Hill and Velani in 1995. However, until recently, little more was known about the Hausdorff measure of these particular sets. In this paper we provide a complete characterisation of the Hausdorff measure of these sets, obtaining a dichotomy for the Hausdorff measure which is determined by the convergence or divergence of a sum depending on the radii of our "shrinking targets". Our main result complements earlier work of Levesley, Salp, and Velani~(2007), and recent work of Baker (2019).
