Aims
The aim of this course is to realize a deep study of univalent functions, which are essential in geometric function theory.
Content
1. Univalent functions. Area Theorem. Covering and distortion theorems.
2. Holomorphic functions with positive real part. herglotz formula. Integral representations. Subordination.
3. Classes of univalent functions. Starlike functions, convex functions, alpha-convex functions, spirallike functions, typically real functions. Meromorphic functions.
4. Differential subordinations. Fundamental lemmas. The class of admissible functions. Applications.
