In this paper, we study the existence of nodal solutions for the Kirchhoff-type problem with concave-convex nonlinearities a+bΩ|u|2dxΔu=λ|u|q1u+|u|p1uin Ω,u=0on Ω, where Ω is a bounded domain with smooth boundary Ω in RN(N=1,2,3), a 0<q<1, 3<p<5. By constraining the energy functional of the above problem on a subset of the nodal Nehari set Mλ, we show that there exists a constant λ>0 such that for any λ<λ, the above problem has a nodal solution uλ with positive energy.

具有凹凸非线性的基尔霍夫型问题的节点解

在本文中,我们研究了具有凹凸非线性的 Kirchhoff 型问题的节点解的存在性 -一种+Ω||2dXΔ=λ||q-1+||-1一世n Ω,=0n Ω, 其中 Ω 是具有平滑边界的有界域 Ω电阻N(N=1,2,3), 一种 0<q<1, 3<<5. 通过将上述问题的能量泛函约束在节点 Nehari 集的一个子集上λ,我们证明存在一个常数 λ>0 使得对于任何 λ<λ,上述问题有节点解 λ 带着正能量。
