  • Complex differentiability, Cauchy-Riemann differential equations,
  • Fundamentals of curve theory (curve length, curvature, number of turns) and curve integrals.
  • Cauchy integral theorems and corollaries
  • Isolated singularities, elementary holomorphic functions, meromorphic functions, Laurent series, residue theorem with applications,
  • submanifolds of R^n (this topic can be treated by the lecturer alternatively in Analysis II)
  • classical vector analysis (gradient, divergence, rotation), differential forms,
  • integration on submanifolds, classical integral theorems (Stokes, Gauss, Ostrogradski ...), applications.

Qualification Goals

Students will be able to,

  • use complex-analytic methods to solve problems in real analysis,
  • deal with complex-differentiable functions used in complex and algebraic geometry,
  • apply integral theorems as a tool for describing various phenomena in mathematical physics (field theory, fluid mechanics, etc.),
  • to reflect knowledge from the basic module Analysis and to consider it in connection with algebra, geometry and topology,
  • to proceed according to mathematical working methods (developing mathematical intuition and its formal justification, training the ability to abstract),
  • can speak freely about scientific content, both in front of an audience and in a discussion.


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

This page describes a module according to the latest valid module guide in Winter semester 2023/24. 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.
