• Opis:
  In this paper we are concerned with the problem of finding solutions for the following nonlinear field equation $$ -\Delta u + V(hx)u-\Delta_{p}u+ W'(u)=0, $$ where $u:\mathbb R^{N}\rightarrow \mathbb R^{N+1}$, $N\geq3$, $p&gt; N$ and $h&gt; 0$. We assume that the potential $V$ is positive and $W$ is an appropriate singular function. In particular we deal with the existence of solutions obtained as critical (not minimum) points for the associated energy functional when $h$ is small enough. Such solutions will eventually exhibit some notable behaviour as $h\rightarrow 0^{+}$. The proof of our results is variational and consists in the introduction of a modified (penalized) energy functional for which mountain pass solutions are studied and soon after are proved to solve our equation for $h$ sufficiently small. This idea is in the spirit of that used in M. Del Pino and P. Felmer [< i> Local mountain passes for semilinear elliptic problems in unbounded domains< /i> , Calc. Var. Partial Differential Equations < b> 4< /b> (1996), 121–137], [< i> Semi-classical states for nonlinear Schrödinger equations< /i> , J. Funct. Anal. < b> 149< /b> (1997), 245–265] and [< i> Multi-peak bound states for nonlinear Schrödinger equations< /i> , Ann. Inst. H. Poincaré Anal. Non Linéaire < b> 15< /b> (1998), 127–149], where "local mountain passes" are found in certain nonlinear Schrödinger equations.
