The subject of univalent functions is an important area within the venerable field of complex analysis. In this subject one often considers subclasses of the class of all analytic and univalent functions defined on the unit disk in the complex plane that are normalized. A more challenging problem is to determine a region of variability for a given subclass. Region of variability problems typically give more exact information about a family of univalent functions than classical growth distortion and rotation theorems. This book deals with a number of region of variability problems defined on...
