On the endpoint estimate for discrete spherical average over sparse sequences

Sanghyuk Lee, Ji Li, Chong-Wei Liang +2

Let $d \geq 5$ , and let $A_{λ}$ denote the normalized discrete spherical average on $Z^{d}$ with squared radius $λ$ . For a strictly increasing sequence $(μ_{k})$ of positive intege…

On the Hausdorff measure of projections of self-similar sets

Chong-Wei Liang

For $0 < d \leq 1/4$ , let $C (d)$ be the four-corner Cantor set with Hausdorff dimension $s_{d} = lo g 4/ lo g (1/ d)$ . Peres, Simon, and Solomyak, as well as Mattila, asked for whic…

Two-weight commutators for the Bessel Riesz transform with Andersen--Kerman weights

Ji Li, Chong-Wei Liang, Chaojie Wen +1

Let $α > - 1/2$ , $α \neq = 0$ , and let $Δ_{α} = - \frac{d ^{2}}{d x ^{2}} - \frac{2 α}{x} \frac{d}{d x}$ be the Bessel operator on $R_{+} = (0, \infty)$ . We characterize boundedness and compactness…

Peres--Schlag's nonempty-interior problem and a shifted-product variant for product sets

Guo-Dong Hong, Chong-Wei Liang, Chun-Yen Shen

We study finite-field analogues of the Peres--Schlag nonempty-interior problem for product sets. Given $A\subseteq\mathbb F_p$, we ask when a suitable one-dimensional linear imag…

On the Peres--Schlag orthogonal projection problem and Kakeya-type sets

Guo-Dong Hong, Chong-Wei Liang, Chun-Yen Shen

We investigate the Peres--Schlag nonempty interior problem for orthogonal projections in both the finite-field and Euclidean settings. Over finite fields $F_{q}^{n}$ , we employ…

A curved three-point pattern problem for fractal sets on the real line

Surjeet Singh Choudhary, Chong-Wei Liang, Chun-Yen Shen

We study the occurrence of curved three-point configurations in fractal subsets of the real line. We prove that if $E \subset [0,1]$ is a compact set with sufficiently large Haus…

Haar bases for multi-parameter twisted structures

Ji Li, Chong-Wei Liang, Brett D. Wick +2

Motivated by the Cauchy--Szegő projections on a broad class of Siegel domains and the geometric quotient structures of nilpotent Lie groups observed by Nagel, Ricci, and Stein, we…

Maximal functions with twisted structures, distribution inequality and applications

Ji Li, Chong-Wei Liang, Chaojie Wen +1

Motivated by the geometric reduction of Cauchy--Szegő projections on quadratic surfaces of higher codimension (Nagel--Ricci--Stein, 2001) and recent developments on the real-variab…

Twisted Multiparameter singular integrals -- real variable methods and applications, I

Zunwei Fu, Ji Li, Chong-Wei Liang +2

In this paper, we introduce a class of twisted multiparameter singular integrals on $R^{2 m}$ , motivated by the Cauchy--Szegő projections and the solving operators for $\ba…

The Brascamp--Lieb inequality on compact Lie groups and its extinction on homogeneous Lie groups

Michael G. Cowling, Ji Li, Chong-Wei Liang

We study the Brascamp--Lieb inequalities on locally compact nonabelian groups and the Brascamp--Lieb constants $BL (G, σ, p)$ associated to a Brasca…
