The Discrete and Continuous Markus-Yamabe Stability Conjectures
Abstract
We study the discrete and continuous versions of the Markus- Yamabe Conjecture for polynomial vector fields in R^n (especially when n = 3) of the form X = \lambda I+H where \lambda is a real number, I the identity map, and H a map with nilpotent Jacobian matrix JH. We consider the case where the rows of JH are linearly dependent over R and that where they are linearly independent over R. In the former, we find non-linearly triangularizable vector fields X for which the origin is a global attractor for both the continuous and the discrete dynamical systems generated by X. In the independent continuous case, we present a family of vector fields which have orbits escaping to infinity. In the independent discrete case, we present a large family of vector fields which have a periodic point of period 3.
