| This paper deals with following Kirchhoff-type system with critical growth(?),where(?).The first chapter,firstly the research background and present situation of Kirch-hoff system at home and abroad are introduced.Secondly,the main results are given.The second chapter,the main notations,propositions and definitions of the system are given.In chapter three,by the minimization argument on the nodal Nehari manifold and the quantitative deformation lemma,we demonstrate that the above sysytem has a least energy nodal solution. |
