MULTIPLICITY RESULTS FOR SOME FOURTH ORDER ELLIPTIC EQUATIONS
Main Article Content
In this paper we consider the Dirichlet problem for an
fourth order elliptic equation on a open set in R^N . By using vari-
ational methods we obtain the multiplicity of nontrivial weak solu-
tions for the fourth order elliptic equation.
