The Schwarzian derivative and the Wiman-Valiron propertyTools Langley, James (2016) The Schwarzian derivative and the Wiman-Valiron property. Journal d'Analyse Mathématique, 130 (1). pp. 71-89. ISSN 1565-8538 Full text not available from this repository.AbstractConsider a transcendental meromorphic function in the plane with finitely many critical values, such that the multiple points have bounded multiplicities and the inverse function has finitely many transcendental singularities. Using the Wiman-Valiron method it is shown that if the Schwarzian derivative is transcendental then the function has infinitely many multiple points, the inverse function does not have a direct transcendental singularity over infinity, and infinity is not a Borel exceptional value. The first of these conclusions was proved by Nevanlinna and Elfving via a fundamentally different method.
