Capacitary Trapping and Brownian Escape: A Sharp Hardy Principle for Absorbing Media

Yiqun Chen, Jie Xiao, Dachun Yang +2

We study Brownian motion killed upon exiting arbitrary open sets $Ω \subset R^{n}$ , $n \in [3, \infty) \cap N$ . Let $α \in (0, 1]$ . The infimal radius $d_{α} (x)$ at which the abs…

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 matrix-weighted multi-parameter Besov--Triebel--Lizorkin-type spaces

Fan Bu, Yiqun Chen, Tuomas Hytönen +2

We develop a comprehensive theory for a general class of multi-parameter function spaces of Besov-Triebel-Lizorkin type, with a matrix weight. We prove the equivalence of different…
