Abstract
In this paper,we study the existence of solutions for Kirchhoff equation-(a+b∫(R)3|▽u|2dx)△u=λu+μ|u|q-2u+|u|p-2u,x ∈(R)3 with mass constraint condition Sc:={u ∈ H1((R)3):∫(R)3|u|2dx=c},where a,b,c>0,μ ∈(R),2<q<p<6,and λ ∈(R)appears as a Lagrange multiplier.For the range of p and q,the Sobolev critical exponent 6 and mass critical exponent 14/3 are involved where corresponding energy functional is unbounded from below on Sc.We consider the focusing case,i.e.,μ>0 when(p,q)belongs to a certain domain in (R)2.We prove the existence of normalized solutions by using constraint minimization,concentration compactness principle and Minimax methods.We partially extend the results which have been studied.
