A bifurcation theorem for noncoercive integral functionals

Comment.Math.Univ.Carolinae 45,3 (2004) 443-456.

Abstract:In this paper we study the existence of critical points for noncoercive functionals, whose principal part has a degenerate coerciveness. A bifurcation result at zero for the associated differential operator is established.

Keywords: critical points, noncoercive and nondifferentiable functionals, bifurcation \break points
