Solvability of nonlinear elliptic equations with gradient terms
We study the solvability in the whole Euclidean space of coercive quasi-linear and fully nonlinear elliptic equations modeled on $ u\pm g(|\nabla u|)= f(u)$, $u\ge0$, where $f$ and $g$ are increasing continuous functions. We give conditions on $f$ and $g$ which guarantee the availability or the absence of positive solutions of such equations in $\R^N$.

Multiscale Finite Element Methods for Nonlinear Problems and their Applications [PDF]
In this paper we propose a generalization of multiscale finite element methods (Ms-FEM) to nonlinear problems. We study the convergence of the proposed method for nonlinear elliptic equations and propose an oversampling technique.

A nonlinear elliptic equation with singular potential and applications to nonlinear field equations
We study existence and asymptotic properties of solutions to a semilinear elliptic equation in the whole space. The equation has a cylindrical symmetry and we find cylindrical solutions. The main features of the problem are that the potential has a large set of singularities (i.e. a subspace), and that the nonlinearity has a double power-like behaviour,

Uniqueness for Neumann problems for nonlinear elliptic equations
In the present paper we prove uniqueness results for solutions to a class of Neumann boundary value problems whose prototype is --div((1 + |$\nabla$u| 2) (p--2)/2 $\nabla$u) -- div(c(x)|u| p--2 u) = f in $ $, (1 + |$\nabla$u| 2) (p--2)/2 $\nabla$u + c(x)|u| p--2 u $\times$ n = 0 on $\partial$$ $,

In this paper, we study a nonlinear Dirichlet problem of p-Laplacian type with combined effects of nonlinear singular and convection terms. An existence theorem for positive solutions is established as well as the compactness of solution set.

Nonlinear elliptic equations with subhomogeneous potentials
Abstract We prove the existence of nonnegative symmetric solutions to the semilinear elliptic equation − △ u + V ( | y 1 | , … , | y k | ) u = g ( u ) in R N where x = ( z , y 1 , … , y k ) ∈ R N 0 × R N 1 × ⋯ × R N

Continuity of solutions of a nonlinear elliptic equation [PDF]
We consider a nonlinear elliptic equation of the form div [a (∇u )] + F [u ] = 0 on a domain Ω, subject to a Dirichlet boundary condition tru = φ . We do not assume that the higher order term a satisfies growth conditions from above. We prove the existence of continuous solutions either when Ω is convex and φ satisfies a one-sided bounded slope ...
