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

open access: yesJournal 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

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

open access: yesFractal 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]

open access: yes, 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 ...

Multiple commutator formulas [PDF]

open access: yesIsrael Journal of Mathematics, 2012
Let A be a quasi-finite R-algebra (i.e., a direct limit of module finite algebras) with identity. Let I_i, i=0,...,m, be two-sided ideals of A, \GL_n(A,I_i) the principal congruence subgroup of level I_i in GL_n(A) and E_n(A,I_i) be the relative elementary subgroup of level I_i.

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

open access: yesEntropy, 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 ...
