摘要:

In this paper, we concern with the following fourth order elliptic equations of Kirchhoff type
???11???
where a,b>0 are constants and the primitive of the nonlinearity f is of superlinear growth near infinity in u and is also allowed to be sign-changing. By using variational methods, we establish the existence and multiplicity of solutions. Our conditions weaken the Ambrosetti-Rabinowitz type condition.

关键词: fourth order elliptic equations of Kirchhoff type, symmetric mountain pass theorem, variational methods
