Commutators with Lipschitz Functions and Nonintegral Operators

open access: yesJournal of Applied Mathematics, 2013
Let T be a singular nonintegral operator; that is, it does not have an integral representation by a kernel with size estimates, even rough. In this paper, we consider the boundedness of commutators with T and Lipschitz functions.

The Route to Artery Mimetics: Hybrid Bioinks for Embedded Bioprinting of Multimaterial Cylindrical Models

open access: yesAdvanced Functional Materials, EarlyView.
The fabrication of a cellularized, multilayered 3D printed cylindrical model comprising hybrid bioinks inspired by the natural extracellular environment as an approach to artery mimetics, is presented. Using embedded bioprinting, interlayer crosslinking of self‐supporting concentric cylinders is achieved.

The CRITERII NOETHERIENE PENTRU ECUAŢII INTEGRALE SINGULARE PERTURBATE CU OPERATORI CU NUCLEE OMOGENE

open access: yesStudia Universitatis Moldaviae: Stiinte Umanistice, 2007
In this paper one class of perturbated integral singular operators with homogeneous kernels operators is studied. The Noetherian criteries and formulas for the calculation of indexes of these operators are established.

Norm inequalities for higher-order commutators of one-sided oscillatory singular integrals

open access: yesJournal of Inequalities and Applications, 2016
In the present paper, we study the weighted norm inequalities for higher-order commutators formed by a class of one-sided oscillatory singular integrals and B M O $BMO$ functions. We obtain that the boundedness of these commutators can be deduced by that

On the regularity of inverses of singular integral operators [PDF]

open access: yesDuke Mathematical Journal, 1988
Let G be a connected, simply connected Lie group with graded Lie algebra of homogeneous dimension D. Denote by \(L^ r_{\gamma}\) the natural left-invariant Sobolev space of order \(\gamma\) (with respect to \(L^ r(G))\). The author proves the following result.

High‐Performance Low‐Emissivity Paints Enabled by N‐Doped Poly(benzodifurandione) (n‐PBDF) for Energy‐Efficient Buildings

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a scalable and colored low‐emissivity (low‐e) paint achieved by spraying an ultrathin n‐doped poly(benzodifurandione) (n‐PBDF) coating onto various colored substrates. The low‐e paint enhances thermal regulation by reducing mid‐infrared thermal emissivity to 0.19, thereby stabilizing indoor temperatures across diverse climates ...

A higher-order singularity subtraction technique for the discretization of singular integral operators on curved surfaces

open access: yes, 2013
This note is about promoting singularity subtraction as a helpful tool in the discretization of singular integral operators on curved surfaces. Singular and nearly singular kernels are expanded in series whose terms are integrated on parametrically ...

The Structure of Algebras of Singular Integral Operators

open access: yesJournal of Integral Equations and Applications, 1992
Application of local principles made it possible to get a deep insight into the Banach algebra \(P\Sigma_ \Gamma^ p(\alpha)\) generated by singular integral operators with Cauchy kernel on a composed curve \(\Gamma=\bigcup_{j=1}^ N \Gamma_ j\) (\(\Gamma_ j\) are smooth Lyapunov curves with only endpoints in common) and piecewise continuous coefficients
