Qualification Goals

The students shall

  • learn to recognize and assess the relevance of approximation theory for practical problems, e.g. from numerical analysis, and to acquire the approximation theoretical tools to solve these problems,
  • learn how methods of linear algebra, analysis and numerical analysis interact,
  • Re-evaluate knowledge from the basic modules and some advanced modules,
  • to recognise the relations of approximation theory to other areas of mathematics and to other sciences,
  • practice mathematical working methods (development of mathematical intuition and its formal justification, training of the ability to abstract, proof techniques),
  • 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.
