Global behaviour of polynomial differential systems in the positive orthant

Abstract : We study polynomial n-dimensional differential systems defined in the positive orthant. By using tools from positivity and functions that decrease along the trajectories, we give sufficient conditions for a regular global behaviour: that is, all the trajectories eiter converge towards the equilibria or are unbounded. We also give results on global stability or unstability in some cases.
