Two characterizations of central BMO space via the commutators of Hardy operators

, 2021
This article addresses two characterizations of BMO⁢(ℝn){\mathrm{BMO}(\mathbb{R}^{n})}-type space via the commutators of Hardy operators with homogeneous kernels on Lebesgue spaces: (i) characterization of the central BMO⁢(ℝn){\mathrm{BMO}(\mathbb{R}^{n})

Commutators of Cauchy-Szego type integrals for domains in C^n with minimal smoothness

, 2021
In this paper we study the commutator of Cauchy type integrals C on a bounded strongly pseudoconvex domain D in C with boundary bD satisfying the minimum regularity condition C as in the recent result of Lanzani–Stein.

Commutativity and Homotopy-Commutativity [PDF]

open access: possible, 1964
The aim of this section is to show, by means of the methods developed in Chapter 3, that for an associative H-space G there exist maps G× G → G satisfying certain commutativity conditions (Theorem 4.5). As will be explained in Remarks 4.6 this result is related to the work of other authors on homotopy-commutativity.

On compactness of commutators of multiplication and bilinear pseudodifferential operators and a new subspace of BMO

, 2020
It is known that the compactness of the commutators of point-wise multiplication with bilinear homogeneous Calderon–Zygmund operators acting on product of Lebesgue spaces is characterized by the multiplying function being in the space CMO.

Boundedness of commutators of fractional integral operators on mixed Morrey spaces

Integral transforms and special functions, 2019
In this paper, we give the necessary and sufficient conditions for the boundedness of commutators of fractional integral operators on mixed Morrey spaces. We construct the predual spaces of mixed Morrey spaces.

Two Weight Commutators on Spaces of Homogeneous Type and Applications

Journal of Geometric Analysis, 2018
In this paper, we establish the two weight commutator theorem of Calderón–Zygmund operators in the sense of Coifman–Weiss on spaces of homogeneous type, by studying the weighted Hardy and BMO space for $$A_2$$ A 2 weights and by proving the sparse ...

Commutators of maximal functions on spaces of homogeneous type and their weighted, local versions

Frontiers of Mathematics in China, 2019
We obtain the characterizations of commutators of several versions of maximal functions on spaces of homogeneous type. In addition, with the aid of interpolation theory, we provide weighted version of the commutator theorems by establishing new ...

On the compactness of oscillation and variation of commutators

Banach Journal of Mathematical Analysis, 2019
In this paper, we first establish the weighted compactness result for oscillation and variation associated with the truncated commutator of singular integral operators. Moreover, we establish a new CMO(Rn)\documentclass[12pt]{minimal} \usepackage{amsmath}
