On the differentiability of solutions of quasilinear elliptic equations [PDF]

open access: yesColloquium Mathematicum, 1993
The author gives a simpler proof of a result of \textit{Yu. G. Reshetnyak} [Sib. Mat. Zh. 28, No. 4(164), 193-195 (1987; Zbl 0679.35018)], which states that a weak solution of the quasilinear elliptic equation \(\text{div } A(x,u, \nabla u)= B(x,u, \nabla u)\), \(x\in \Omega\subset \mathbb{R}^ n\), is differentiable almost everywhere.

Nonexistence of stable solutions to quasilinear elliptic equations on Riemannian manifolds

open access: yes, 2016
We prove nonexistence of nontrivial, possibly sign changing, stable solutions to a class of quasilinear elliptic equations with a potential on Riemannian manifolds, under suitable weighted volume growth conditions on geodesic ...

Monotonicity and symmetry of singular solutions to quasilinear problems

open access: yes, 2018
We consider singular solutions to quasilinear elliptic equations under zero Dirichlet boundary condition. Under suitable assumptions on the nonlinearity we deduce symmetry and monotonicity properties of positive solutions via an improved moving plane ...

A Picone identity for variable exponent operators and applications

open access: yesAdvances in Nonlinear Analysis, 2019
In this work, we establish a new Picone identity for anisotropic quasilinear operators, such as the p(x)-Laplacian defined as div(|∇ u|p(x)−2 ∇ u).

Quasilinear elliptic equations with subquadratic growth

open access: yesJournal of Differential Equations, 2006
AbstractIn this paper we consider nonlinear boundary value problems whose simplest model is the following:(0.1){−Δu+ν|u|p−1u=γ|∇u|2θ+f(x)inΩ,u=0on∂Ω, where f(x) is a summable function in Ω (bounded open set in RN, N>2), p>θ(1−θ ...

Existence of positive solutions for generalized quasilinear Schrödinger equations with Sobolev critical growth

open access: yesElectronic Journal of Qualitative Theory of Differential Equations
In this paper, we are devoted to establishing that the existence of positive solutions for a class of generalized quasilinear elliptic equations in $\mathbb{R}^{N}$ with Sobolev critical growth, which have appeared from plasma physics, as well as high ...

Nonlinear Hodge maps

open access: yes, 2000
We consider maps between Riemannian manifolds in which the map is a stationary point of the nonlinear Hodge energy. The variational equations of this functional form a quasilinear, nondiagonal, nonuniformly elliptic system which models certain kinds of ...

Some regularity results for anisotropic motion of fronts [PDF]

open access: yes, 2002
We study the regularity of propagating fronts whose motion is anisotropic. We prove that there is at most one normal direction at each point of the front; as an application, we prove that convex fronts are C^{1,1}.
