Matrix-Weighted Besov-Type and Triebel--Lizorkin-Type Spaces III: Characterizations of Molecules and Wavelets, Trace Theorems, and Boundedness of Pseudo-Differential Operators and Calderón--Zygmund Operators
Fan Bu, Tuomas Hytönen, Dachun Yang +1
This is the last one of three successive articles by the authors on matrix-weighted Besov-type and Triebel--Lizorkin-type spaces and …
Matrix-Weighted Besov-Type and Triebel--Lizorkin-Type Spaces II: Sharp Boundedness of Almost Diagonal Operators
Fan Bu, Tuomas Hytönen, Dachun Yang +1
This article is the second one of three successive articles of the authors on the matrix-weighted Besov-type and Triebel--Lizorkin-type spaces. In this article, we obtain the sharp…
New Characterizations and Properties of Matrix Weights
Fan Bu, Tuomas Hytönen, Dachun Yang +1
We provide several new characterizations of -matrix weights, originally introduced by A. Volberg as matrix-valued substitutes of the classical weights. In…
A unified approach to self-improving property via K-functionals
Oscar Dominguez, Yinqin Li, Sergey Tikhonov +2
In this paper we obtain new quantitative estimates that improve the classical inequalities: Poincaré-Ponce, Gaussian Sobolev, and John-Nirenberg. Our method is based on the K-funct…
