内容介绍：This talk investigates the existence of infinitely many nodal solutions for the following Schr?dinger-Poisson system with zero-mass. By establishing a radial decay inequality in the radial Coulomb space, for any positive integer we demonstrate that the system possesses a radial nodal solution that changes sign exactly times. We also prove that the energy of such solution is an increasing function of In particular, the inequality paves the way for the study of nodal solutions to the Schr?dinger-Poisson-Slater equations. The results presented here were joint work with Cui Zhang.
