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.

Semi-commutations and Partial commutations [PDF]

RAIRO - Theoretical Informatics and Applications, 2000
The aim of this paper is to show that a semi-commutation function can be expressed as the compound of a sequential transformation, a partial commutation function, and the reverse transformation. Moreover, we give a necessary and sufficient condition for the image of a regular language to be computed by the compound of two sequential functions and a ...

Spherical Tuples of Hilbert Space Operators [PDF]

, 2014
We introduce and study a class of operator tuples in complex Hilbert spaces, which we call spherical tuples. In particular, we characterize spherical multi-shifts, and more generally, multiplication tuples on RKHS.

Writing commutators of commutators as products of cubes [PDF]

Communications in Algebra, 2021
It is known that commutators of commutators can be written as products of cubes, with the current upper bound on the number of cubes being 60. We discuss how proofs extracted via coset enumeration can be used to investigate this problem, and exhibit a rewriting using only 14 cubes.

Boundedness of rough singular integral operators and commutators on Morrey-Herz spaces with variable exponents

Journal of Inequalities and Applications, 2016
By decomposing functions, we establish some boundedness results for some rough singular integrals on the homogeneous Morrey-Herz spaces M K ˙ q , p ( ⋅ ) α ( ⋅ ) , λ ( R n ) $M\dot{K}_{q, p(\cdot)}^{\alpha(\cdot),\lambda}({\Bbb{ R}}^{n})$ , where the two
