Infinitely many sign-changing solutions for Kirchhoff type problems in ${\mathbb{R}}^3$

Jijiang Sun, Lin Li, Matija Cencelj +1

In this paper, we consider the following nonlinear Kirchhoff type problem: \[ \left\{\begin{array}{lcl}-\left(a+b\displaystyle\int_{\mathbb{R}^3}|\nabla u|^2\right)Δu+V(x)u=f(u), &…
