Critical points of some classical Euler-Lagrange functionals related to

-Δ*u* = *f*(*u*)

belong to an hypersurface of
*H ^{1}_{0}*(Ω),
the so-called Nehari manifold.
In this talk we present a description of it using elementary tools of
differential geometry. Also, we analise the behaviour of "angular
decreasing" flows in the case where

*f*is homogeneous. Our results reflect an intermediate stage of research.
