Qualification Goals

The students

  • know elements of the theory of Hopf algebras,
  • view familiar abstract mathematical structures from a new perspective,
  • are able to analyze unfamiliar abstract structures using unfamiliar methods,
  • are proficient in dealing with tensors,
  • have deepened mathematical working methods (developing mathematical intuition and its formal justification, abstraction, proof),
  • have improved their oral communication skills in lecture and tutorials by practicing free speech in front of an audience and in discussion.

Prerequisites

None. The competences taught in the following modules are recommended: either Algebra [Bachelor Module] or Algebra [Lehramt Module].
