Boundedness of Calderon-Zygmund singular integral operators from l1(Lp) into weak - l1(Lp) [PDF]

open access: yesInternational Journal of Mathematical Analysis, 2021
In this paper, we prove that Calderón-Zygmund singular integral operators are bounded from amalgam space l1(Lp) into weak amalgam space weak - l1(Lp), as well as from lq(Lp) into itself where 1 < q < p < ∞.

On boundedness of fractional maximal operator in weighted L^p(.) spaces [PDF]

open access: yesMathematical Inequalities & Applications, 2016
In this paper, we derive some sufficient conditions for the boundedness of the fractionalmaximal operator in the weighted variable exponent Lebesgue spaces Lp(.), where Sawyer’stype pair of modular conditions are proposed on a weight functions and it is assumed a local logregularityand a decay condition on the exponent function p(.).

On the LP boundedness of Marcinkiewicz integrals

open access: yesMichigan Mathematical Journal, 2002
Let \(b \in L^{\infty}(\mathbb R_{+})\) and let \(\Omega \in L^1(S^{n-1})\) with zero average where \(n \geq 2\). For a suitable mapping \(\Phi : \mathbb R^n \rightarrow \mathbb R^d\), the Marcinkiewicz integral operator \(\mu_{\Phi, \Omega, b}\) on \(\mathbb R^d\) is defined by \[ \mu_{\Phi, \Omega, b} f(x) = \Bigl( \int_0^{\infty}| F_{\Phi, t}(x) |^2

On the LP boundedness of h-Fourier integral operators with rough symbols

open access: yesMathematica Montisnigri, 2022
We prove LP boundedness of a class of semiclassical Fourier integral operators defined by smooth phase function and semiclassical rough symbols on the spatial variable 𝑥. We also consider a spacial case of ℎ -pseudodifferential operators.

The Improvement on the Boundedness and Norm of a Class of Integral Operators on Lp Space

open access: yesJournal of Function Spaces, 2015
We prove the condition “c is neither 0 nor a negative integer” can be dropped on the boundedness of a class of integral operators Sa,b,c on Lp space, which improves the result by Krues and Zhu.
