Abstract:

A complex number $z$ is in the final set of an analytic function $f$, as defined by Pólya, if every neighborhood of $z$ contains zeros of infinitely many ${f^{(n)}}$. If $f$ is a Hadamard gap series, then the part of the final set in the open disk of convergence is the origin along with a union of concentric circles.
