Endpoint Estimates for Fractional Hardy Operators and Their Commutators on Hardy Spaces

open access: yesJournal of Function Spaces, 2014
(Hpℝn,Lqℝn) bounds of fractional Hardy operators are obtained. Moreover, the estimates for commutators of fractional Hardy operators on Hardy spaces are worked out.

Some weighted inequalities for Hausdorff operators and commutators

open access: yesJournal of Inequalities and Applications, 2018
In this paper, we consider the problem of boundedness of Hausdorff operator on weighted central Morrey spaces. In particular, we obtain sharp bounds for Hausdorff operators on power weighted central Morrey spaces. Analogous results for the commutators of

Counting Commutators [PDF]

open access: yesTransactions of the American Mathematical Society, 1974
Let G be a group generated by x and y, G 2 {G_2} be the commutator subgroup of G, and G 1 {G_1} be the group generated by y and G 2 {G_2} . This paper contains explicit expansions of

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

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.

Multilinear fractional integral operators on non-homogeneous metric measure spaces

open access: yesJournal 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 ...

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 ...

Notes on pseudodifferential operators commutators and Lipschitz functions

open access: yesOpen Mathematics, 2023
This article focuses on the boundedness of the commutators generated by pseudodifferential operators with Lipschitz functions and obtains a sufficient condition such that these operators are bounded from Lp(Rn){L}^{p}\left({{\bf{R}}}^{n}) into the ...
