  • Complex differentiability, Cauchy-Riemann differential equations
  • Power series, Taylor expansion
  • Curve integrals, Cauchy's integral theorems
  • Isolated singularities, elementary holomorphic functions, meromorphic functions, Laurent series
  • Residue theorem and applications
  • Conform maps, Möbius group
  • Normal families, Montel's theorem
  • Riemann mapping theorem

Qualification Goals

The students shall

  • understand how complex-analytical methods help to solve real-analytical problems,
  • deepen their understanding of the elementary functions through the complex viewpoint,
  • learn about the connections between methods of geometry, algebra, and analysis, as well as topology and number theory, and thus develop their mathematical understanding,
  • Learn methods and skills that are central to applications in computer science (e.g. coding theory), physics (e.g. quantum theory) and engineering (e.g. electrical engineering)
  • practice mathematical working methods (development of mathematical intuition and its formal justification, training of abstraction, proof methods),
  • improve their oral communication skills in the recitation class by practicing free speech in front of an audience and during discussion.


None. The competences taught in the following modules are recommended: either Linear Algebra I and Linear Algebra II or Basic Linear Algebra, either Analysis I and Analysis II or Basic Real Analysis.

Please note:

This page describes a module according to the latest valid module guide in Wintersemester 2022/23. Most rules valid for a module are not covered by the examination regulations and can therefore be updated on a semesterly basis. The following versions are available in the online module guide:

The module guide contains all modules, independent of the current event offer. Please compare the current course catalogue in Marvin.
