Existence of Solutions for the Nonlinear Schrödinger Equation with V (∞) = 0

  • Chapter
Contributions to Nonlinear Analysis

Abstract

We study the existence of a solution of the problem

$$ \left\{ \begin{gathered} - \Delta u + V\left( x \right)u = f'\left( u \right)x \in \mathbb{R}^N , \hfill \\ u\left( x \right) > 0, \hfill \\ \end{gathered} \right. $$

under the assumption that

$$ \mathop {\lim }\limits_{\left| x \right| \to \infty } V\left( x \right) = 0 $$

where V > 0 and there is no ground state solution.
