Holmes stated the non linear systemx¡§ + x¨B + g(x) = zz¨B + z = xwith the purpose of analysing certain kind of control system of feedback. Taking g(x) =x(x2 1) and x¨B = y a non linear systems is obtained which present a non hyperbolic point in its origin whose stability id being studied. %K Bifurcation %K Non Hyperbolic point %K stability %U http://revistasigma.udenar.edu.co/articulos/articulosIX2/4.pdf
