Ground state solutions of Nehari-Pohozaev type for Schrödinger-Poisson problems with general potentials
Discrete and Continuous Dynamical Systems. Series A
This paper is dedicated to studying the following Schrödinger-Poisson problem where V (x) is weakly differentiable and f ∈ C(R, R). By introducing some new tricks, we prove the above problem admits a ground state solution of Nehari-Pohozaev type and a least energy solution under mild assumptions on V and f . Our results generalize and improve the ones in [D. Ruiz, J. Funct. Anal. ] and some related literature. 2010 Mathematics Subject Classification. 35J10, 35J20. Key words and phrases.

For more details in the physical aspects, we refer the readers to [4, 5] . It is well known that Problem (1.1) can be reduced to a nonlinear Schrödinger equation with a nonlocal term. Indeed, as we shall see in Section 2, for any u ∈ H 1 (R 3 ), there exists a unique φ u ∈ D 1,2 (R 3 ) such that − φ = u 2 by using the Lax-Milgram theorem, then inserted into the first equation, gives
