Abstract

This article concerns with the existence of multiple positive solutions for the following logarithmic Schrödinger equation

$ \left\{ \begin{array}{lc} -{\epsilon}^2\Delta u+ V(x)u = u \log u^2, & \mbox{in} \quad \mathbb{R}^{N}, \\ u \in H^1(\mathbb{R}^{N}), & \; \\ \end{array} \right. $

where $ \epsilon >0 $, $ N \geq 1 $ and $ V $ is a continuous function with a global minimum. Using variational method, we prove that for small enough $ \epsilon>0 $, the "shape" of the graph of the function $ V $ affects the number of nontrivial solutions.
