Pointwise Multipliers for Besov Spaces $B_{p, \infty}^{0, b} (R^{n})$ with Only Logarithmic Smoothness

Ziwei Li, Winfried Sickel, Dachun Yang +1

In this article, we establish a characterization of the set $M (B_{p, \infty}^{0, b} (R^{n}))$ of all pointwise multipliers of Besov spaces $B_{p, \infty}^{0, b} (R^{n})$ wi…

Riesz Transform Characterization of Hardy Spaces Associated with Ball Quasi-Banach Function Spaces

Fan Wang, Dachun Yang, Wen Yuan

Let $X$ be a ball quasi-Banach function space satisfying some mild assumptions and $H_{X} (R^{n})$ the Hardy space associated with $X$ . In this article, the authors introduce b…

The $L^{p}$ -to- $L^{q}$ Compactness of Commutators with $p > q$

Tuomas Hytönen, Kangwei Li, Jin Tao +1

Let $1 < q < p < \infty$ , $\frac{1}{r} := \frac{1}{q} - \frac{1}{p}$ , and $T$ be a non-degenerate Calderón--Zygmund operator. We show that the commutator $[b, T]$ is compact from $L^{p} (R^{n})$ to…

Boundedness of Calderón--Zygmund operators on ball Campanato-type function spaces

Yiqun Chen, Hongchao Jia, Dachun Yang

Let $X$ be a ball quasi-Banach function space on $R^{n}$ satisfying some mild assumptions. In this article, the authors first find a reasonable version $T$ of t…

Real-Variable Characterizations and Their Applications of Matrix-Weighted Triebel--Lizorkin Spaces

Qi Wang, Dachun Yang, Yangyang Zhang

Let $α \in R$ , $q \in (0, \infty]$ , $p \in (0, \infty)$ , and $W$ be an $A_{p} (R^{n}, C^{m})$ -matrix weight. In this article, the authors characterize the matrix-weighted…
