The coefficients of starlike functions [PDF]

open access: yesProceedings of the American Mathematical Society, 1969
disc. The proof of the local maximum theory for the coefficients of univalent functions by Bombieri [2] and by Garabedian and Schiffer [3] gives strength to the conjecture that these dn exist, but no estimate of their size is available from these papers.

Convex and Starlike Meromorphic Functions [PDF]

open access: yesProceedings of the American Mathematical Society, 1980
In this paper we study meromorphic univalent functions with a simple pole at p which map the unit disk onto the exterior of convex sets or the exterior of starlike sets. A question raised by Libera and Livingston concerning the equality of two classes of starlike meromorphic univalent functions is answered. We show that the set of points omitted by the
