Linear and nonlinear convolution elliptic equations [PDF]
Boundary Value Problems, 2013 In this paper, the separability properties of elliptic convolution operator equations are investigated. It is obtained that the corresponding convolution-elliptic operator is positive and also is a generator of an analytic semigroup. By using these results, the existence and uniqueness of maximal regular solution of the nonlinear convolution equation ...

Cloaking and Antennas: From Theoretical Paradigms to Next‐Generation Intelligent Systems
Advanced Optical Materials, EarlyView.The inception of electromagnetic cloaking sparked an immediate question: Can antennas be made invisible? Two decades later, this review charts the intertwined progress of major cloaking strategies (from transformation optics to scattering cancellation), metasurface technology, and their application to antennas, revealing how AI‐enabled devices are ...

Advanced Photonics Research, EarlyView.Electron acceleration using multipetawatt femtosecond lasers and subcritical density plasmas achieves a maximum charge of 245 nC, with an injection rate of up to 100 nC per picosecond. The charge variation with plasma density, initially increasing and then decreasing, arises from the competition between the injection of multiple plasma waves and laser ...

Advanced Photonics Research, EarlyView.Strong resonant amplification in polarization anisotropy in third harmonic generation (THG) response from isolated MoS2 disks with small structural ellipticity introduced during fabrication is reported. This is attributed to the high refractive index of the MoS2 disk that supports characteristic anapole resonances combined with the cubic dependence of ...

Regularity for nonlinear elliptic equations and systems
Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2020 We study the regularity of weak solutions to the elliptic system in divergence form divA(x, Du)=0 in an open set Ω of R^n, n≥2. The vector field A(x.ξ), A: Ω×R^(m×n)→R^(m×n), has a variational nature in the sense that A(x,ξ)= Dξ f(x,ξ), where f:Ω×R^(m×n)→R is a convex Carathéodory integrand; i.e., f=f (x,ξ) is measurable with respect to x∈R^n and it is
