A Poincaré-Bendixson theorem for Bebutov shifts and applications to switched systems
Jairo Bochi, Ian D. Morris
We prove a version of the Poincaré-Bendixson theorem for certain classes of curves on the 2-sphere which are not required to be the trajectories of an underlying flow or semiflow o…
Stability with respect to periodic switching laws does not imply global stability under arbitrary switching
Ian D. Morris
R. Shorten, F. Wirth, O. Mason, K. Wulff and C. King have asked whether a linear switched system is guaranteed to be globally uniformly stable under arbitrary switching if it is kn…
Continuity and approximability of competitive spectral radii
Marianne Akian, Stéphane Gaubert, Loïc Marchesini +1
The competitive spectral radius extends the notion of joint spectral radius to the two-player case: two players alternatively select matrices in prescribed compact sets, resulting…
General real measurable Livšic regularity via transfer operators
Ian D. Morris
We prove a general measurable Livšic regularity theorem for real-valued cocycles over non-invertible dynamical systems using only abstract hypotheses on an associated transfer oper…
