Positive radial solutions of a nonlinear boundary value problem

, 2018
In this work we study the following quasilinear elliptic equation: \begin{document}$\left\{ {\begin{array}{*{20}{l}}{ - {\rm{div}}(\frac{{|x{|^\alpha }\nabla u}}{{{{(a(|x|) + g(u))}^\gamma }}}) = |x{|^\beta }{u^p}}&{{\rm{in}} \ \Omega }\\{u = 0}&{{\rm{on}

Positive radial solutions for a class of quasilinear Schrödinger equations in R3 [PDF]

, 2022
This paper is concerned with the following quasilinear Schrödinger equations of the form: −∆u − u∆(u 2 ) + u = |u| p−2u, x ∈ R 3 where p ∈ (2, 12). By making use of the constrained minimization method on a special manifold, we prove that the existence of

Thermal Cycle–Microstructure–Property Relationships in Rail Steel Heat‐Affected Zone Simulated by Gleeble

Advanced Engineering Materials, EarlyView.
Microstructural evolution of premium rail steel during flash butt welding (FBW), comparing physically simulated heat‐affected zones with actual weld regions. Thermal cycles induce phase transformations and microstructural heterogeneity that influence weld quality and mechanical performance. These findings provide insights into optimizing FBW parameters

Positive radial solutions of n-dimensional elliptic systems with indefinite weight functions and n parameters

Advances in Difference Equations, 2019
Under simple conditions on f and a, we show the existence of positive radial solutions for the n-dimensional elliptic differential system {Δu(x)+Λa(|x|)f(u(x))=0,R10,x∈Rn,n≥2 $\mathbf{x}=(x_{1},x_{2},\ldots ,x_{n})^{T}, \mathbf{u}(\mathbf {x})=(u _{1 ...

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

Advanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Structure of positive radial solutions including singular solutions to Matukuma's equation

Communications on Pure and Applied Analysis, 2005
We consider positive solutions of Matukuma's equation, which is described by a nonlinear elliptic equation with a weight. Any radially symmetric solution of this equation is said to be regular or singular according to its behavior near the origin and infinity. We investigate the structure of positive radial regular and singular solutions.
