Természettudományok subject: 01.01. Matematika description: In this paper we consider the following Schrödinger–Kirchhoff–Poisson-type system where Ω is a bounded smooth domain of R3 , a > 0, b ≥ 0 are constants and λ is a positive parameter. Under suitable conditions on Q(x) and combining the method of invariant sets of descending flow, we establish the existence and multiplicity of signchanging solutions to this problem for the case that 2 < p < 4 as λ sufficiently small. Furthermore, for λ = 1 and the above assumptions on Q(x), we obtain the same conclusions with 2 < p < 12 5. date: 2021 type: Folyóirat type: NonPeerReviewed format: full language: hu identifier: http://acta.bibl.u-szeged.hu/75807/1/ejqtde_2021_086.pdf identifier: Yu Shubin; Zhang Ziheng; Yuan Rong: Sign-changing solutions for a Schrödinger-Kirchhoff-Poisson system with 4-sublinear growth nonlinearity.
