Examination achievement PL1

  • Form of examination: oral examination (20-30 Min.)
  • Examination Frequency: each semester
  • Examination number: 84156 ("Introduction to Tensor Categories")

Evaluation of grades

The grade of the module examination is also the module grade.


  • categories, functors, additive and Abelian categories,
  • monoidal categories and functors,
  • Grothendieck ring, categorisation, example of categorisation of group rings.

In addition, a selection of the following topics:

  • Hopf algebras and quantum groups,
  • graphic calculus for morphisms,
  • braided tensor categories, band categories and knot invariants,
  • modular tensor categories and topological quantum field theories.

Competencies / intended learning achievements

Upon successful completion of this module, the students have learned the fundamentals of category theory, categorical thinking and categorisation. They understand both - the theoretical principles and proofs as well as examples and applications - and are able to understand and explain them.


  • P. Etingof, S. Gelaki, D. Nikshych, V. Ostrik: Tensor Categories,
