DOI: http://dx.doi.org/10.12775/TMNA.2007.012

#### Abstract

The existence and concentration behavior of nodal solutions are

established for the equation $-\varepsilon^{p} \Delta_{p}u +

V(z)|u|^{p-2}u=f(u)$ in $\Omega$, where $\Omega$ is a domain in

${\mathbb R}^{N}$, not necessarily bounded, $V$ is a positive Hölder

continuous function and $f\in C^{1}$ is a function having

subcritical growth.
