Abstract:In this article, we study the existence and multiplicity results for Kirchhoff type equations of the form
   {-(a + b integral(Omega) |del u|(2) dx)Delta u = f(x, u), in Omega, (*)
   u = 0, on partial derivative Omega,
   where f is an element of C((Omega) over bar x R, R) is three-superlinear at infinity. Under certain assumptions on f, we obtain at least one nontrivial solution for (*) without assuming the Ambrosetti and Rabinowitz condition by using the mountain pass theorem, and obtain infinitely many solutions when f(x, .) is odd by using the fountain theorem.
