A NOTE ON MINIMAX RESULTS FOR CONTINUOUS FUNCTIONALS

ALEXANDRU KRISTÁLY, CSABA VARGA

Abstract


In this paper we extend the Willem deformation lemma for continuous functionals and we traite also the equivariant case. With the aid of this results we extend the min-max results of Ghoussoub [21]. As application we give an another proof of some multiplicity results of Corvellec [5] and we give some multiplicity results for continuous functionals which contains a large class of multiplicity results for differentiable and locally Lipschitz functionals.
