Variable Anisotropic Singular Integral Operators

Constructive approximation, 2020
We introduce the class of variable anisotropic singular integral operators associated to a continuous multi-level ellipsoid cover $$\Theta $$ Θ of $$\mathbb {R}^n$$ R n introduced by Dahmen et al. (Constr Approx 31:149–194, 2010). This is an extension of

On a singular integral operator

Russian Mathematical Surveys, 1988
Let D(\(\subset {\mathbb{C}})\) be a bounded domain with the smooth boundary. The authors consider an operator of the form \(A=a(z)I+b(z)K+c(z)S+d(z)KS\) acting in the space \(L^ p(D ...

Boundedness of Toeplitz operators related to singular integral operators

Izvestiya: Mathematics, 2018
We establish that Toeplitz-type operators related to singular integral operators with variable Calderón– Zygmund kernels are bounded on weighted Morrey spaces. To do this, we prove weighted inequalities for the sharp maximal functions of such operators.

Weighted Norm Inequalities for Rough Singular Integral Operators

Journal of Geometric Analysis, 2017
In this paper we provide weighted estimates for rough operators, including rough homogeneous singular integrals $$T_\Omega $$TΩ with $$\Omega \in L^\infty (\mathbb {S}^{n-1})$$Ω∈L∞(Sn-1) and the Bochner–Riesz multiplier at the critical index $$B_{(n-1)/2}

A note on singular integral operators [PDF]

open access: possibleApproximation Theory and its Applications, 1996
Summary: We study the \(L^p\)-boundedness of the singular integral operators of R. Fefferman when the kernel satisfies certain size condition. We also consider the corresponding maximal singular integral operators.
