A Liouville theorem for a class of superlinear elliptic equations on cones
We give sufficient conditions for non-existence of positive solutions of the equation Δu + a(x)u + b(x)up = 0 on a cone of Rn We further analyze the existence of positive solutions in the radial, subcritical case, and show that under suitable conditions ...

We consider a nonlinear elliptic equation driven by the (p, q)–Laplacian plus an indefinite potential. The reaction is (p − 1)–superlinear and the boundary term is parametric and concave.

HARDY-SOBOLEV INEQUALITIES AND HYPERBOLIC SYMMETRY
. — We discuss uniqueness and nondegeneracy of extremals for some weighted Sobolev inequalities and give some applications to Grushin and scalar curvature type equations. The main theme is hyperbolic symmetry.

Existence results for nonlinear anisotropic elliptic partial differential equations with variable exponents [PDF]
The focus of this paper will be on studying the existence of solutions in the sense of distribution, for a class of nonlinear partial differential equations defined by a variable exponent anisotropic elliptic operator with a growth condition given by

© Hindawi Publishing Corp. UNIQUENESS AND RADIAL SYMMETRY FOR AN INVERSE ELLIPTIC EQUATION
We consider an inverse rearrangement semilinear partial differential equation in a 2-dimensional ball and show that it has a unique maximizing energy solution. The solution represents a confined steady flow containing a vortex and passing over a seamount.

Some numerical results of a boundary value problem with nonlinear terms
In this work we consider numerical positive solutions of the equation −Δu = λf (u) with Dirichlet boundary condition in a bounded domain Ω, where λ > 0 and f (u) is a superlinear function of u.
