EXISTENCE AND CONCENTRATION RESULTS FOR KIRCHHOFF-TYPE SCHR¨O DINGER SYSTEMS WITH STEEP POTENTIAL WELL

다국어 초록 (Multilingual Abstract)

In this paper, we consider the following Kirchhoff-type Schr¨odinger system −(a1 + b1 ∫R3 |∇u|2dx)△u + γV (x)u = 2α/α+β|u|α−2u|v|β in R3, −(a2 + b2 ∫R3 |∇u|2dx)△u + γV (x)u = 2β/α+β|u|α|v|β−2v in R3, u, v ∈ H1(R3), where ai and bi are positive constants for i = 1, 2, γ > 0 is a parameter, V (x) and W(x) are nonnegative continuous potential functions. By applying the Nehari manifold method and the concentration-compactness principle, we obtain the existence and concentration of ground state solutions when the parameter γ is sufficiently large.
