Distinguishing endpoint sets from Erdős space

David S. Lipham

We prove that the set of all endpoints of the Julia set of $f (z) = exp (z) - 1$ which escape to infinity under iteration of $f$ is not homeomorphic to the rational Hilbert space $\math…

Erdős space in Julia sets

David S. Lipham

We prove that the rational Hilbert space $E$ , known as Erdős space, surfaces in complex dynamics via iteration of $e^{z} - 1$ .

The topological dimension of radial Julia sets

David S. Lipham

We prove that the meandering set for $f_{a} (z) = e^{z} + a$ is homeomorphic to the space of irrational numbers whenever $a$ belongs to the Fatou set of $f_{a}$ . This extends recent results b…
