Boundedness of p-Adic Hardy Operators and Their Commutators on p-Adic Central Morrey and BMO Spaces

open access: yesJournal of Function Spaces and Applications, 2013
We obtain the sharp bounds of p-adic Hardy operators on p-adic central Morrey spaces and p-adic λ-central BMO spaces, respectively. We also establish the λ-central BMO estimates for commutators of p-adic Hardy operators on p-adic central Morrey spaces.

Global boundedness of a class of multilinear Fourier integral operators

open access: yesForum of Mathematics, Sigma, 2021
We establish the global regularity of multilinear Fourier integral operators that are associated to nonlinear wave equations on products of $L^p$ spaces by proving endpoint boundedness on suitable product spaces containing combinations of the local ...

Large BMO spaces vs interpolation [PDF]

open access: yesAnalysis & PDE, 2015
In this paper we introduce a class of BMO spaces which interpolate with $L_p$ and are sufficiently large to serve as endpoints for new singular integral operators. More precisely, let $( , , )$ be a $ $-finite measure space. Consider two filtrations of $ $ by successive refinement of two atomic $ $-algebras $ _\mathrm{a}, _\mathrm{b}$ having

Littlewood-Paley characterization for Campanato spaces

open access: yesJournal of Function Spaces and Applications, 2006
The Littlewood-Paley characterization for the local approximation Campanato spaces Lpα is well known in the cases α≥0 and α=−np. We give in this paper a characterization of such a type for L2α spaces (and for Morrey-Campanato spaces L2,λ) for any α≥−n2 ...

Precompact Sets, Boundedness, and Compactness of Commutators for Singular Integrals in Variable Morrey Spaces

open access: yesJournal of Function Spaces, 2017
We give sufficient conditions for subsets to be precompact sets in variable Morrey spaces. Then we obtain the boundedness of the commutator generated by a singular integral operator and a BMO function on the variable Morrey spaces.

p-Adic Riesz Potential and Its Commutators on Morrey-Herz Spaces

open access: yesJournal of Function Spaces, 2022
In this paper, we establish the boundedness of p-adic Riesz potential on Morrey-Herz spaces, as well as the λ-central BMO estimates for multilinear commutators of p-adic Riesz potential on Morrey-Herz spaces.

Estimates for the Commutators of p-Adic Hausdorff Operator on Herz-Morrey Spaces

open access: yesMathematics, 2019
In this paper, we investigate the boundedness of commutators of matrix Hausdorff operator on the weighted p-adic Herz-Morrey space with the symbol functions in weighted central bounded mean oscillations (BMO) and Lipschitz spaces.

Pointwise multipliers of weighted BMO spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1993
In a recent paper by S. Bloom (Pointwise multipliers of weighted B M O BMO spaces, Proc. Amer. Math. Soc. 105 (1989), 950-960), there are some inaccuracies. In this note, we give a counterexample to his "theorem" and a corrected form with proof under a suitable condition on weights.

The boundedness of commutators associated with Schrödinger operators on Herz spaces

open access: yesJournal of Inequalities and Applications, 2016
Let L = − Δ + V $L=-\Delta+V$ be a Schrödinger operators on R n $\mathbb{R}^{n}$ , n ≥ 3 $n\geq3$ , where the nonnegative potential V belongs to the reverse Hölder class B s $B_{s}$ for s > d 2 $s>\frac{d}{2}$ . Let T β = ( − Δ + V ) − β V β $T_{\beta}=(-
