Weighted Estimates for Iterated Commutators of Riesz Potential on Homogeneous Groups

open access: yesMathematics, 2021
In this paper, we study the two weight commutators theorem of Riesz potential on an arbitrary homogeneous group H of dimension N. Moreover, in accordance with the results in the Euclidean space, we acquire the quantitative weighted bound on homogeneous ...

Commutative–non-commutative dualities [PDF]

open access: yesCanadian Journal of Physics, 2020
We show that it is in principle possible to construct dualities between commutative and non-commutative theories in a systematic way. This construction exploits a generalization of the exact renormalization group equation (ERG). We apply this to the simple case of the Landau problem and then generalize it to the free and interacting non-canonical ...

Some remarks on the sparse dominations for commutators of multi(sub)linear operator

open access: yesJournal of Inequalities and Applications, 2021
We establish pointwise sparse dominations for the iterated commutators of multi(sub)linear operators satisfying the W q $W_{q}$ condition. As consequences, we present some quantitative weighted estimates for the commutators.

Semi-commutations and Partial commutations [PDF]

open access: yesRAIRO - Theoretical Informatics and Applications, 2000
Summary: 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 ...

Weighted Lipschitz estimates for commutators of multilinear Calderón–Zygmund operators with Dini type kernels

open access: yesJournal of Inequalities and Applications, 2022

Some estimates for commutators of bilinear pseudo-differential operators

open access: yesOpen 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.

Associativity as commutativity [PDF]

open access: yesJournal of Symbolic Logic, 2006
AbstractIt is shown that coherence conditions for monoidal categories concerning associativity are analogous to coherence conditions for symmetric strictly monoidal categories, where associativity arrows are identities. Mac Lane's pentagonal coherence condition for associativity is decomposed into conditions concerning commutativity, among which we ...
