Unbounded solutions for Schrodinger quasilinear elliptic problems with perturbation by a positive non-square diffusion term

Carlos Alberto Santos, Jiazheng Zhou

Abstract:
In this article, we present a version of Keller-Osserman condition for the Schr\"odinger quasilinear elliptic problem
$$\displaylines{ -\Delta u+\frac{k}{2}u\Delta u^2=a(x)g(u)\quad\text{in } \mathbb{R}^N,\cr u>0\quad \text{in }\mathbb{R}^N,\quad \lim_{|x|\to \infty} u(x)= \infty\,, }$$
where $a:\mathbb{R}^N \to [0,\infty)$ and $g:[0,\infty) \to [0,\infty)$ are suitable continuous functions, $N \geq 1$, and $k>0$ is a parameter. By combining a dual approach and this version of Keller-Osserman condition, we show the existence and multiplicity of solutions.
