New weighted norm inequalities for multilinear Calderón–Zygmund operators with kernels of Dini’s type and their commutators

open access: yesJournal of Inequalities and Applications, 2021
In this paper, we introduce certain classes of multilinear Calderón–Zygmund operators with kernels of Dini’s type. Applying the sharp method and A p → ∞ ( φ ) $A_{\vec{p}}^{\infty }(\varphi )$ functions, we first establish some weighted norm inequalities

A Class of Commutators for Multilinear Fractional Integrals in Nonhomogeneous Spaces

open access: yesJournal of Inequalities and Applications, 2008
Let μ be a nondoubling measure on ℝd. A class of commutators associated with multilinear fractional integrals and RBMO(μ) functions are introduced and shown to be bounded on product of Lebesgue spaces with μ.

Multilinear Estimates for Calderón Commutators

open access: yesInternational Mathematics Research Notices, 2018
AbstractIn this paper, we investigate the multilinear boundedness properties of the higher ($n$-th) order Calderón commutator for dimensions larger than two. We establish all multilinear endpoint estimates for the target space $L^{\frac{d}{d+n},\infty }(\mathbb{R}^d)$, including that Calderón commutator maps the product of Lorentz spaces $L^{d,1 ...
