# An Integral Representation Formula of the Schwarzian Derivative

An Integral Representation Formula of the Schwarzian Derivative Let f be a conformal map of the unit disk D onto a domain bounded by a curve C, which is of class C 3,δ, except for a finite number of corners. In this paper we derive a representation formula of the Schwarzian derivative S f, expressed in terms of the integral of the arclength derivative of the curvature of C and a sum of polar terms corresponding to the vertices. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Computational Methods and Function Theory Springer Journals

### Abstract

Let f be a conformal map of the unit disk D onto a domain bounded by a curve C, which is of class C 3,δ, except for a finite number of corners. In this paper we derive a representation formula of the Schwarzian derivative S f, expressed in terms of the integral of the arclength derivative of the curvature of C and a sum of polar terms corresponding to the vertices.
