Abstract:
This talk deals with existence and multiplicity results of positive solutions for the quasilinear Schr\odinger equation \begin{align*} \left\{\begin{array}{c} \displaystyle-\Delta u-\lambda m(x) u\Delta(u^2)=f(\mu,x,u)\text{ in }\Omega, \ u=0\text{ on }\partial\Omega. \end{array}\right. \end{align*} where $\Omega$ is a bounded open domain in $\mathbb{R}^N$ with smooth boundary and $m$ is bounded positive continuous function. Under suitable assumptions on $f$ and asymptotically linear behaviour, we can use bifurcation theory in order to give an analysis on the set of positive solutions.
