报告摘要：In this talk, we are concerned with the existence, non-existence and multiplicity of positive normalized solutions (λ_c,u_c )∈R×H^1 (R^N) to the following Kirchhoff problem

-(a+b∫_(R^N)▒〖|∇u|^2 dx〗)Δu+λu=g(u),x∈R^N,N≥1

satisfying the normalization constraint ∫_(R^N)▒〖|u|^2 dx=c〗>0. The nonlinearity g is allowed to be subcritical or critical at infinity. In particular, the higher dimension case N≥5 is also considered and such problems lack the mountain pass geometry due to the presence of the non-local term ∫_(R^N)▒〖|∇u|^2 dx〗. This talk is based on joint works with Xiaoyu Zeng(WUT), Yimin Zhang(WUT), Jian Zhang(UPC) and Xuexiu Zhong(SCNU).
