New matrix-weighted norm inequalities and extrapolation

Guixiang Hong, Pengfei Yin

In this paper, we propose a new type of matrix-weighted theory and show the corresponding Rubio de Francia extrapolation theorems by means of noncommutative maximal inequalities. W…

Vector-valued Littlewood--Paley--Rubio de Francia Inequalities on Vilenkin Systems

Deyu Chen, Guixiang Hong

We investigate two natural formulations of equal-length Littlewood--Paley--Rubio de Francia (LPR) inequalities on arbitrary Vilenkin systems \(\Gm\). The canonical formulation uses…

Campanato spaces via quantum semigroups

Guixiang Hong, Yuanyuan Jing, Ping Li

In this paper, we continue to investigate Campanato spaces via semigroups on von Neumann algebras. One of the main results is their coincidence with Lipschitz spaces for {\it all}…

Vector-valued partial sums on unbounded Vilenkin systems

Deyu Chen, Guixiang Hong

Let \(\Gm=\prod_{k\ge0}\mathbb Z_{m_k}\) be a Vilenkin group that is not necessarily bounded, i.e., \(\sup_k m_k=\infty\). We prove that, for every UMD Banach space \(X\) and every…

The nonlinear estimates on quantum Besov spaces

Deyu Chen, Guixiang Hong

The superposition operators have been widely studied in nonlinear analysis, which are essential for the well-posedness theory of nonlinear equations. In this paper, we investigate…

Navier-Stokes Equations on Quantum Euclidean Spaces

Deyu Chen, Guixiang Hong, Liang Wang +1

We investigate in the present paper the Navier-Stokes equations on quantum Euclidean spaces with being a antisymmetric matrix, which is a standard…

Noncommutative ergodic theorems for action of semisimple Lie groups

Guixiang hong, Samya Kumar Ray

Let be a connected simple Lie group of real rank one and finite center, and let be a maximal compact subgroup. We study the families of spherical, ball, and uniform average…

Campanato spaces via quantum Markov semigroups on finite von Neumann algebras

Guixiang Hong, Yuanyuan Jing

We study the Campanato spaces associated with quantum Markov semigroups on a finite von Neumann algebra . Let be a Markov semigroup, $\mat…

Operator-Valued Hardy spaces and BMO Spaces on Spaces of Homogeneous Type

Zhijie Fan, Guixiang Hong, Wenhua Wang

Let be a von Neumann algebra equipped with a normal semifinite faithful trace, be a space of homogeneous type in the sense of Coifman and Weiss…

A Representation of Matrix-Valued Harmonic Functions by the Poisson Integral of Non-commutative BMO Functions

Cheng Chen, Guixiang Hong, Wenhua Wang

In this paper, the authors study the matrix-valued harmonic functions and characterize them by the Poisson integral of functions in non-commutative BMO (bounded mean oscillation) s…
