Abstract

We prove that the set of all endpoints of the Julia set of f(z)=exp(z)1f(z)=\exp(z)-1 which escape to infinity under iteration of ff is not homeomorphic to the rational Hilbert space E\mathfrak E. As a corollary, we show that the set of all points zCz\in \mathbb C whose orbits either escape to \infty or attract to 00 is path-connected. We extend these results to many other functions in the exponential family.
