Multiple positive solutions for Kirchhoff problems with sign-changing potential
Electronic Journal of Differential Equations, 2015 In this article, we study the existence and multiplicity of positive solutions for a class of Kirchhoff type equations with sign-changing potential. Using the Nehari manifold, we obtain two positive solutions.

Multiple solutions for quasilinear elliptic equations with sign-changing potential [PDF]
Electronic Journal of Differential Equations, 2016 In this article, we study the quasilinear elliptic equation $$ -\Delta_{p} u-(\Delta_{p}u^{2})u+ V (x)|u|^{p-2}u=g(x,u), \quad x\in \mathbb{R}^N, $$ where the potential V(x) and the nonlinearity g(x,u) are allowed to be sign-changing.

Subcritical perturbations of resonant linear problems with sign-changing potential [PDF]
Electronic Journal of Differential Equations, 2005 We establish existence and multiplicity theorems for a Dirichlet boundary-value problem at resonance. This problem is a nonlinear subcritical perturbation of a linear eigenvalue problem studied by Cuesta, and includes a sign-changing potential. We obtain

Multiple solutions for an indefinite Kirchhoff-type equation with sign-changing potential
Electronic Journal of Differential Equations, 2015 In this article, we study a Kirchhoff-type equation with sign-changing potential on an infinite domain. Using Morse theory and variational methods, we show the existence of two and of infinitely many nontrivial solutions.

The ATIS sign language corpus [PDF]
, 2008 Systems that automatically process sign language rely on appropriate data. We therefore present the ATIS sign language corpus that is based on the domain of air travel information. It is available for five languages, English, German, Irish sign language,
