The twisted rabbit problem is a polynomial classification problem: the goal is to determine equivalence types of functions of complex numbers that are not given by a formula (these are called topological polynomials). The problem arises out of complex dynamics and the first solution given by Bartholdi and Nekrashevych used group theory. But we give a topological solution – one that classifies topological polynomials by their invariant trees. This is joint work with Jim Belk, Justin Lanier, and Dan Margalit.For more information, call 845-758-7266, or e-mail [email protected].
