### Course description and aims

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.

### Student learning outcomes

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.

### Competencies that will be developed

 ✔ Specialist skills Intercultural skills Communication skills Critical thinking skills ✔ Practical and/or problem-solving skills

### Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.

None.
