Abstract

This paper deals with a fourth order elliptic equation on compact Riemannian manifolds, the function ƒ involved in the nonlinearity is of changing sign which makes the analysis more difficult than the case where ƒ is of constant sign.We prove the multiplicity of solutions in the subcritical case which is the subject of the first theorem. In the second one we establish the existence of solutions to the equation with critical Sobolev growth.

Keywords
