Symbolic dynamics for nonhyperbolic systems
David Richeson, Jim Wiseman
We introduce index systems, a tool for studying isolated invariant sets of dynamical systems that are not necessarily hyperbolic. The mapping of the index systems mimics the expans…

Itineraries of rigid rotations and diffeomorphisms of the circle
David Richeson, Paul Winkler, Jim Wiseman
We examine the itinerary of under the rotation by $α\in\R\bs\Q$. The motivating question is: if we are given only the itinerary of 0 relative to …
