Abstract:

In this paper, we focus on dealing with a class of critical Kirchhoff type equation

{(a+bR4|u|2dx)Δu+λV(x)u=|u|2u+f(u) in R4,uH1(R4),

where a,b>0 are constants and λ>0. The nonlinear growth of |u|2u reaches the Sobolev critical exponent since 2=4 in dimension 4. Assume that V is the nonnegative continuous potential, which represents a potential well with the bottom V1(0) and fC(R,R) satisfies suitable conditions. By the variational methods, the existence of at least a ground state solution is obtained. Moreover, we study the concentration behavior of the ground state solutions as λ and their asymptotic behavior as b0 and λ, respectively.

Key words: Kirchhoff type equation, critical growth, variational methods, steep potential well, ground state solutions
