RESUMO

In this work, we studied a certain proprieties of invariant sets of descending flow defined by pseudogradient vector field. This analysis permit us to determine the existence and multiplicity of critical points of certain functionals bounded below in invariant sets by associate flow. We applied this concepts to nonlinear elliptic boundary value problems and nonlinear systems of ordinary differential equations. In variant cases, at least four solutions are obtained for these equations.
