Mixed local and nonlocal critical Schrodinger-Kirchhoff-Poisson type systems with logarithmic perturbation

Shengbing Deng, Guorong Zeng

Abstract:
In this article, we consider the mixed local and nonlocal critical Schrodinger-Kirchhoff-Poisson type system with logarithmic perturbation $$\displaylines{ - M(\int_{\Omega}|\nabla u|^2\,dx)\Delta u+a(-\Delta)^{s}u+\lambda\phi u =\eta |u|^{q-2}u\ln|u|^2+|u|^4u, \quad \text{in }\Omega, \cr -\Delta\phi=u^2,\quad \text{in }\Omega,\cr \phi=u=0,\quad \text{in } \mathbb{R}^3\setminus\Omega. }$$ where \(\Omega\subset\mathbb{R}^3\) is a bounded domain with smooth boundary, \(00\) are two parameters, \(M(t)=a+bt\) and \(a,b\) are nonnegative constants. With the help of variational methods, the existence of a non-trivial ground state solution is obtained.
