Atomic Characterization and Its Applications of Matrix-Weighted Variable Hardy Spaces

Yiqun Chen, Dachun Yang, Wen Yuan +1

In this article, by means of the matrix-weighted grand maximal function we first introduce the variable Hardy space $H_{W}^{p (\cdot)}$ on $R^{n}$ with the $\mathscr{A}_{p(\cdo…

Real-Variable Theory of Hardy--Lorentz Spaces on Quasi-Ultrametric Spaces of Homogeneous Type with Reverse-Doubling Property

Chenfeng Zhu, Ryan Alvarado, Xianjie Yan +2

Let $(X, q, I^¼)$ be an ultra-RD-space with upper dimension $n \in (0, \infty)$ ; i.e., it is a quasi-ultrametric space of homogeneous type whose measure $I^¼$ satisfies an additi…
