Orbit Portraits in non-Autonomous Iteration
Mark Comerford, Todd Woodard
We extend the definition of an orbit portrait to the context of non-autonomous iteration, both for the combinatorial version involving collections of angles and for the dynamic ver…

Preservation of External Rays in non-Autonomous Iteration
Mark Comerford, Todd Woodard
We consider the dynamics arising from the iteration of an arbitrary sequence of polynomials with uniformly bounded degrees and coefficients and show that, as parameters vary within…
