Nontrivial solutions to Serrin's problem in annular domains [PDF]
Annales de l'Institut Henri Poincaré C, Analyse non linéaire, 2021 We construct nontrivial bounded, real analytic domains \mathrm{\Omega } \subseteq \mathbb{R}^{n} of the form \mathrm{\Omega }_{0} \setminus \overline{\mathrm{\Omega }}_{1} , bifurcating from annuli, which admit a positive solution to ...

A characterization of annular domains by quadrature identities [PDF]
Bulletin of the London Mathematical Society, 2019 The authors verify a conjecture by Armitage and Goldstein (cf. [\textit{D. A. Brannan} and \textit{W. K. Hayman}, Bull. Lond. Math. Soc. 21, No. 1, 1--35 (1989; Zbl 0695.30001)]) which states that annular domains can be characterized as quadrature domains for harmonic functions with respect to a uniformly distributed measure on the sphere.

Subwavelength resolution of the annular photonic crystal with negative refraction [PDF]
Journal of the European Optical Society-Rapid Publications, 2012 In this paper, negative refraction in the two-dimensional (2D) hexagonal lattices annular photonic crystal (APC) was theoretically studied. The annular photonic crystal was obtained by introduced circular-air-hole in the core of the Si-rod.

Acute annular outer retinopathy preceded by invasive ductal breast carcinoma: a case report
BMC Ophthalmology, 2022 Background Acute annular outer retinopathy (AAOR) is an uncommon disease. To date, there are few documented cases in the literature. Our case report is the first to describe a case of acute annular outer retinopathy in a patient with invasive ductal ...

Existence of Positive Solutions to Singular Boundary Value Problems Involving φ-Laplacian
Mathematics, 2019 This paper is concerned with the existence of positive solutions to singular Dirichlet boundary value problems involving φ -Laplacian. For non-negative nonlinearity f = f ( t , s ) satisfying f ( t , 0 ) ≢ 0 , the existence of an
