Multilinear commutators in the two‐weight setting [PDF]

Bulletin of the London Mathematical Society, 2020
We extend the recently much‐studied two‐weight commutator estimates to the multilinear setting. In contrast to previous results, our result respects the multilinear nature of the problem fully and is formulated with the genuinely multilinear weights.

Regularity of Commutators of the One-Sided Hardy-Littlewood Maximal Functions

Journal of Function Spaces, 2020
In this paper, the regularity properties of two classes of commutators of the one-sided Hardy-Littlewood maximal functions and their fractional variants are investigated.

Some weighted estimates for the commutators of p-adic Hardy operator on two weighted p-adic Herz-type spaces

AIMS Mathematics, 2021
In the present artice we discuss the weighted p-adic central bounded mean oscillations (CMO) and p-adic Lipschtiz estimates for the commutators of p-adic Hardy operator on two weighted p-adic Herz-type spaces.

Some estimates for commutators of bilinear pseudo-differential operators

Open Mathematics, 2022
We obtain a class of commutators of bilinear pseudo-differential operators on products of Hardy spaces by applying the accurate estimates of the Hörmander class. And we also prove another version of these types of commutators on Herz-type spaces.

Weighted estimates for commutators associated to singular integral operator satisfying a variant of Hörmander's condition

AIMS Mathematics, 2023
In this paper, we establish some boundedness for commutators generated by the singular integral operator satisfying a variant of Hörmander's condition and a weighted BMO function on weighted Hardy spaces and weighted Herz spaces.

Operators with commutative commutants.

Michigan Mathematical Journal, 1988
Given operators M and N on a Hilbert space H, suppose that M (resp. N) is the direct sum of k (resp. n) copies of an operator A having a commutative commutant. Suppose further that m and k are countable cardinalities (or, any cardinalities if H is separable) and that N is a quasi-affine transform of M (i.e., \(NX=XM\) for some injective operator X with

XMO and Weighted Compact Bilinear Commutators [PDF]

Journal of Fourier Analysis and Applications, 2019
To study the compactness of bilinear commutators of certain bilinear Calderón–Zygmund operators which include (inhomogeneous) Coifman–Meyer bilinear Fourier multipliers and bilinear pseudodifferential operators as special examples, Torres and Xue (Rev ...

Fractional operators and their commutators on generalized Orlicz spaces [PDF]

Opuscula Mathematica, 2022
In this paper we examine boundedness of fractional maximal operator. The main focus is on commutators and maximal commutators on generalized Orlicz spaces (also known as Musielak-Orlicz spaces) for fractional maximal functions and Riesz potentials.
