Intended learning outcomes

After the course the student should be able to

  • Understand, interpret and use the basic concepts: complex number, analytic function, harmonic function, Taylor and Laurent series, singularity, residue, conformal mapping, meromorphic function.
  • Prove certain fundamental theorems about analytic functions, e.g. Cauchy’s integral formula
  • Determine the stability of certain dynamical systems using the Nyqvist criterion
  • Use conformal mapping to solve certain applied problems regarding heat conduction, electrical engineering and fluid mechanics.
  • Use Taylor and Laurent expansions to derive properties of analytic and meromorphic functions.
  • Compute integrals by means of residues.
  • Analyze zeros and poles of meromorphic functions, classify singularities.

In order to get a higher the student should also be able to

  • Explain the theory of analytic functions and prove the most important theorems.

Course main content

  • Meromorphic and analytic functions of one complex variable. Basic transcendental functions, harmonic functions.
  • Integration in the complex plane, Cauchy’s theorem, Cauchy’s integral formula and consequences thereof. Residues.
  • Taylor and Laurent series, zeros and poles, the principle of the argument.
  • Conformal mapping and applications.
