Resumen
By one hand, we continue with the study of the liaison between the almost Hurwitz vector fields and density functions. In particular by using maps H with nilpotent Jacobian JH such that their rows are linearly dependent over R, we construct a family of almost Hurwitz vector fields F in dimension larger than two which has the origin as almost global attractor. This last fact is shown by associating an appropriate density function to the vector field F. Moreover, we show new examples of Hurwitz vector fields such that the origin is a global attractor. On the other hand, in the case when the rows of JH are linearly independent over R, we show explicitly the inverse maps of the counterexamples to Generalized Dependence Problem and proving that this inverse maps preserve the linearly independence over R of the nilpotent Jacobian.
