### Existence and asymptotic behaviour of ground state solutions for quasilinear Schrödinger-Poisson systems in $\mathbb R^3$

#### Abstract

In this paper, we are concerned with existence and asymptotic behavior of ground state in the whole space $\mathbb{R}^3$ for quasilinear Schrödinger-Poisson systems $$\begin{cases} -\Delta u+u+K(x)\phi(x)u=a(x)f(u), & x\in \mathbb{R}^3, \\ -\mbox{div}[(1+\varepsilon^4|\nabla\phi|^2)\nabla\phi]=K(x)u^2, & x\in \mathbb{R}^3, \end{cases}$$ when the nonlinearity coefficient $\varepsilon\gt 0$ goes to zero, where $f(t)$ is asymptotically linear with respect to $t$ at infinity. Under appropriate assumptions on $K$, $a$ and $f$, we establish existence of a ground state solution $(u_\varepsilon, \phi_{\varepsilon, K}(u_\varepsilon))$ of the above system. Furthermore, for all $\varepsilon$ sufficiently small, we show that $(u_\varepsilon, \phi_{\varepsilon, K}(u_\varepsilon))$ converges to $(u_0, \phi_{0, K}(u_0))$ which is the solution of the corresponding system for $\varepsilon=0$.
