“…The author in [50] describes two simple variants of the Nose-Hoover oscillator, the first of which satisfies the original goal exactly, and the second of which exhibits a hidden global chaotic attractor that fills all of its three-dimensional state space. The author in [45] states that during the last six years or so, several exciting papers have discussed systems with line segments of equilibria or planes of equilibria, and systems with more general configurations. It draws attention to the fact that such equilibria were considered previously by Miklos Farkas , in papers published in 1984-2005.…”
