  • Complex differentiability, Cauchy Riemann differential equations,
  • Basic theory of curves (curve length, curvature, winding number) and curve integrals
  • Cauchy integral theorems and consequences
  • Isolated singularities, elementary holomorphic functions, meromorphic functions, Laurent series, residue theorem with applications,
  • Submanifolds of R^n, classical vector analysis (gradient, divergence, rotation), differential forms,
  • Integration on submanifolds, classical integral theorems (Stokes, Gauss, Ostrogradski ...), applications

Qualification Goals

The students shall:

  • learn complex-analytic methods for solving real-analytic problems,
  • practice the handling of complex-differentiable functions, which are used in complex and algebraic geometry,
  • be able to use integral theorems as a tool for describing various phenomena of mathematical physics (field theory, fluid mechanics, etc.),
  • deepen the knowledge from the basic module Analysis and learn connections to algebra, geometry and topology,
  • practice mathematical working methods (development of mathematical intuition and its formal justification, training of abstraction skills),
  • improve their oral communication skills in the exercises by practicing free speech in front of an audience and during 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.
