A note on a global stability theorem of M. W. Hirsch
Ji Fa Jiang · Proceedings of the American Mathematical Society · 1991
For a 3 3 -dimensional cooperative vector field F F , we present a new global stability result which is the same as that of Hirsch [4] except that we do not assume that Div F ≤ 0 \operatorname {Div} F \leq 0 or that the equilibrium is stable. Thus we solve the "interesting problem" pointed out by Hirsch [4].
