摘要

In this paper, we consider the qualitative analysis of solutions for the following Kirchhoff equation with Hardy nonlinearities: {(a+bRN|u|2dx)Δu=λu+|u|p2u|x|β+μ|u|q2u|x|β, in RN,RNu2dx=c2,\( \left \{\begin{aligned} &-(a+b\int _{\mathbb{R}^{N}}|\nabla u|^{2} dx)\Delta u=\lambda u+\frac{|u|^{p - 2}u}{|x|^{\beta}}+\mu \frac{|u|^{q - 2}u}{|x|^{\beta}}, &&\text{ in } \mathbb{R}^{N},\\ &\int _{\mathbb{R}^{N}} u^{2} dx = c^{2}, \end{aligned}\right . \) where N3,0<β<2,2<q<p<2β:=2(Nβ)N2$N\geq 3,~0<\beta <2,~2<q<p<2^{*}_{\beta}:=\frac{2(N-\beta )}{N-2}$, a,b,c>0,μ>0$a,b,c>0,~\mu >0$ and λR$\lambda \in \mathbb{R}$ appears as a Lagrange multiplier. By developing a perturbed Pohozaev constraint approach, we show the existence of normalized solutions under the mixed L2$L^{2}$-critical case where 2<q<2(N+4β)N<p<2β$2< q<\frac{2(N+4-\beta )}{N}<p<2^{*}_{\beta}$ and ground state solutions in the L2$L^{2}$-supercritical case where 2(N+4β)N<q<p<2β$\frac{2(N+4-\beta )}{N}< q< p<2^{*}_{\beta}$, respectively. Moreover, the asymptotic behaviors of the normalized solutions are also obtained.
