Spectrality of factors of product spectral measures

Mihail N. Kolountzakis, Chun-Kit Lai, Kailing Lai +1

We refine the method by Greenfeld and Lev for the product spectral set problem and generalize the theorem to a singular measure setting. Furthermore, we establish a new class of sp…

Quantitative Hardy--Littlewood maximal inequalities and Wiener--Stein theorem on p.c.f. fractals

Long Huang, Jinjun Li, Xiaofeng Wang

Let $K \subset R^{d}$ be a post-critically finite (p.c.f.) self-similar set with Hausdorff dimension $s$ , and $μ$ be a self-similar probability measure supported on $K$ . Let…

Spectra of the Sierpiński type spectral measure and their Beurling dimensions

Jinjun Li, Zhiyi Wu

In this paper, we study the structure of the spectra for the Sierpiński type spectral measure $μ_{A, D}$ on $R^{2}$ . We give a sufficient and necessary condition fo…
