Existence of Multiple Nontrivial Solutions for a Strongly Indefinite Schrödinger-Poisson System
Keyword(s):
We consider a Schrödinger-Poisson system inℝ3with a strongly indefinite potential and a general nonlinearity. Its variational functional does not satisfy the global linking geometry. We obtain a nontrivial solution and, in case of odd nonlinearity, infinitely many solutions using the local linking and improved fountain theorems, respectively.
