Estimates for a Rough Fractional Integral Operator and Its Commutators on p-Adic Central Morrey Spaces

Fractal and Fractional, 2022
In the current paper, we obtain the boundedness of a rough p-adic fractional integral operator on p-adic central Morrey spaces. Moreover, we establish the λ-central bounded mean oscillations estimate for commutators of a rough p-adic fractional integral ...

Upper Bound for Multi-parameter Iterated Commutators [PDF]

, 2015
We show that the product BMO space can be characterized by iterated commutators of a large class of Calder\'on-Zygmund operators. This result follows from a new proof of boundedness of iterated commutators in terms of the BMO norm of their symbol ...

Multilinear fractional integral operators on non-homogeneous metric measure spaces

Journal of Inequalities and Applications, 2016
In this paper, the boundedness in Lebesgue spaces for multilinear fractional integral operators and commutators generated by multilinear fractional integrals with an RBMO ( μ ) $\operatorname{RBMO}(\mu)$ function on non-homogeneous metric measure spaces ...

The boundedness of variation associated with the commutators of approximate identities

Journal of Inequalities and Applications, 2021
In this paper, we establish L p $L^{p}$ -boundedness and endpoint estimates for variation associated with the commutators of approximate identities, which are new for variation operators.

Normalities and commutators

Journal of Algebra, 2010
We first compare several algebraic notions of normality, from a categorical viewpoint. Then we introduce an intrinsic description of Higgins' commutator for ideal-determined categories, and we define a new notion of normality in terms of this commutator. Our main result is to extend to any semi-abelian category the following well-known characterization

A Method for Choosing an Initial Time Eigenstate in Classical and Quantum Systems

Entropy, 2013
A subject of interest in classical and quantum mechanics is the development of the appropriate treatment of the time variable. In this paper we introduce a method of choosing the initial time eigensurface and how this method can be used to generate time ...

On Commuting and Noncommuting Complexes [PDF]

Journal of Algebra, 2001
In this paper we study various simplicial complexes associated to the commutative structure of a finite group G. We define NC(G) (resp. C(G)) as the complex associated to the poset of pairwise non-commuting (resp. commuting) sets in G. We observe that NC(G) has only one positive dimensional connected component, which we call BNC(G), and we prove that ...

Endpoint boundedness for commutators of singular integral operators on weighted generalized Morrey spaces

Journal of Inequalities and Applications, 2020
In this paper, we obtain the endpoint boundedness for the commutators of singular integral operators with BMO functions and the associated maximal operators on weighted generalized Morrey spaces.
