Abstract:
New distortion theorems are proved for holomorphic univalent functions bounded in a circular annulus and preserving one of its boundary components. In particular, inequalities including the Schwarzian derivative at a boundary point of the annulus are established. All results follow from the properties of the conformal capacity of condensers and symmetrization.
Keywords:
univalent function, angular derivative, Schwarzian derivative,
condenser capacity, symmetrization.
