چکیده
where K, h ∈ L(R), a(x) is a positive bounded function, and f(s) is asymptotically linear with respect to s at infinity, that is f(s)/s goes to a constant as s → +∞. Under suitable assumptions on K, a and f , we prove that the problem (P) has at least two positive solutions for |K|2 and |h|2 small by using Ekeland’s variational principle and Mountain pass theorem.

Existence of non-trivial solutions for fractional Schrödinger-Poisson systems with subcritical growth
In this paper, we are concerned with the following fractional Schrödinger-Poisson system: (−∆s)u + u + λφu = µf(u) +|u|p−2|u|, x ∈R3 (−∆t)φ = u2, x ∈R3 where λ,µ are two parameters, s,t ∈ (0,1] ,2t + 4s > 3 ,1 < p ≤ 2∗ s and f : R → R is continuous function. Using some critical point theorems and truncation technique, we obtain the existence and multiplicity of non-trivial solutions with ...

متن کاملExistence of positive solutions to Schrödinger–Poisson type systems with critical exponent
The existence of positive solutions to Schrödinger–Poisson type systems in R 3 with critically growing nonlocal term is proved by using variational method which does not require usual compactness conditions. A key ingredient of the proof is a new Brézis–Lieb type convergence result.

In this article, by using variational method, we study the existence of a positive ground state solution for the Schrödinger-Poisson system −∆u+ V (x)u+K(x)φu = f(x, u), x ∈ R, −∆φ = K(x)u, x ∈ R, where V (x),K(x) and f(x, u) are asymptotically periodic functions in x at infinity.
متن کاملExistence and multiplicity of positive solutions to Schrödinger–Poisson type systems with critical nonlocal term
The existence, nonexistence and multiplicity of positive radially symmetric solutions to a class of Schrödinger–Poisson type systems with critical nonlocal term are studied with variational methods. The existence of both the ground state solution and mountain pass type solutions are proved. It is shown that the parameter ranges of existence and nonexistence of positive solutions for the critica...
