Period-Doubling Cascades Invariants: Braided Routes To Chaos
Eran Igra, Valerii Sopin
By a classical result of Kathleen Alligood and James Yorke we know that as we isotopically deform a map to a Smale horseshoe map we should often expect the…

Essential dynamics in chaotic attractors
Eran Igra
We prove that if a smooth vector field of generates a sufficiently complicated heteroclinic knot, the flow also generates infinitely many periodic orbits, which persist u…

Removable dynamics in the Nose-Hoover and Moore-Spiegel Oscillators
Eran Igra
We study the dynamics of the Nose-Hoover and Moore-Spiegel Oscillators, and in particular, their topological dynamics. We prove the dynamics of both these systems can be reduced to…
