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…

A compact extension of Journé's $T 1$ theorem on product spaces

Mingming Cao, Kôzô Yabuta, Dachun Yang

We prove a compact version of the $T 1$ theorem for bi-parameter singular integrals. That is, if a bi-parameter singular integral operator $T$ admits the compact full and partial ke…

Boundedness of Fractional Integrals on Hardy Spaces Associated with Ball Quasi-Banach Function Spaces

Yiqun Chen, Hongchao Jia, Dachun Yang

Let $X$ be a ball quasi-Banach function space on $R^{n}$ and $H_{X} (R^{n})$ the Hardy space associated with $X$ , and let $α \in (0, n)$ and $β \in (1, \infty)$ . In this art…

Mixed-Norm Herz Spaces and Their Applications in Related Hardy Spaces

Yirui Zhao, Dachun Yang, Yangyang Zhang

In this article, the authors introduce a class of mixed-norm Herz spaces, $E ˙_{q}^{α, p} (R^{n})$ , which is a natural generalization of mixed Lebesgue s…

John-Nirenberg inequalities for parabolic BMO

Juha Kinnunen, Kim Myyryläinen, Dachun Yang

We discuss a parabolic version of the space of functions of bounded mean oscillation related to a doubly nonlinear parabolic partial differential equation. Parabolic John-Nirenberg…

Brezis--Van Schaftingen--Yung Formulae in Ball Banach Function Spaces with Applications to Fractional Sobolev and Gagliardo--Nirenberg Inequalities

Feng Dai, Xiaosheng Lin, Dachun Yang +2

Let $X$ be a ball Banach function space on $R^{n}$ . In this article, under some mild assumptions about both $X$ and the boundedness of the Hardy--Littlewood maximal operato…
