Multi-peak Positive Solutions To A Class Of Kirchhoff Equations In R~3

In this thesis,we consider the following Kirchhoff equation-(?2? + ?b?R3|?u|2dx)?u+V(x)u =up,u>0,x?R3,where a,b are positive constants,1<p<5 and ?>0 is a parameter.Under some suit-able assumptions on the potential function V(x),applying the Lyapunov-Schmidt reduction method we prove that the equation above has a positive multi-peak solu-tion concentrating at a critical point of V(x)for ?>0 sufficiently small.
