Course overview and goals
The goal of this course is to outline the new epoch of classical complex analysis. First, we discuss the normal family, and we will show Riemann's mapping theorem which has many applications in the complex analysis. We will explain Riemann surfaces. The theory of Riemann surfaces provides a new foundation for complex analysis on a higher level. As in elementary complex analysis, the subject matter is analytic functions. But the notion of an analytic function will have now a broader meaning as we show.
Course description and aims
By the end of this course, students will be able to:
1) obtain the notion of normal family and its applications.
2) know Riemann's mapping theorem and its applications.
3) understand Riemann surfaces.
Keywords
Normal family, Riemann's mapping theorem, Riemann surface.
