An Endpoint Estimate for the Commutators of Singular Integral Operators with Rough Kernels [PDF]
Potential Analysis, 2020 Let Ω be homogeneous of degree zero and have mean value zero on the unit sphere S ^ d − 1, T _Ω be the homogeneous singular integral operator with kernel Ω ( x ) | x | d $\frac {\Omega (x)}{|x|^{d}}$ and T _Ω, b be the commutator of T _Ω with symbol b ...

On the Commutator of Marcinkiewicz Integrals with Rough Kernels in Variable Morrey-Type Spaces
Ukrainian Mathematical Journal, 2020 Within the framework of variable-exponent Morrey and Morrey–Herz spaces, we prove some boundedness results for the commutator of Marcinkiewicz integrals with rough kernels.

A Note on Marcinkiewicz Integrals along Submanifolds of Finite Type
Journal of Function Spaces, 2018 We study the parametric Marcinkiewicz integrals along submanifolds of finite type with rough kernels. The kernels of our operators are allowed to be very rough both on the unit sphere and in the radial direction. Under the rather weakened size conditions

Journal of Inequalities and Applications, 2007 We give the L2 estimates for the Marcinkiewicz integral with rough variable kernels associated to surfaces. More precisely, we give some other sufficient conditions which are different from the conditions known before to warrant that the L2-boundedness ...

Rough Multilinear Fractional Integrals on Weighted Morrey Spaces
Journal of Function Spaces, 2015 It is showed that a class of multilinear fractional operators with rough kernels, which are similar to the higher-order commutators for the rough fractional integrals, are bounded on the weighted Morrey spaces.

PaddyCheck—An Instrument for Rice Quality Determination
Instruments, 2018 Several of the rice quality parameters are nowadays determined manually or partly manually, which leads to subjective results. In order to analyse the rice quality and avoid most of the manual handling, the PaddyCheck instrument was mainly developed to ...

On the boundedness of parabolic maximal operators on product domains
Heliyon, 2021 In this article, appropriate sharp Lp bounds for a certain class of rough maximal operators MΩ,γ with mixed homogeneity are established. Specifically, when the function Ω belongs to Lq(Sm−1×Sn−1) with m,n≥2 and q>1, the boundedness of the such operators ...
