Evaluation of grades

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


  • regular sequences, depth, projective dimension,
  • reflexive modules,
  • Fitting ideals,
  • Cohen-Macaulay rings and modules,
  • regular and normal rings,
  • complete intersections,

  • algorithmic aspects.

Competencies / intended learning achievements

Upon successful completion of this module, the students have obtained advanced knowledge in commutative ring theory. The tools and methodology acquired opens the doors to some of the most fundamental structures in Algebraic Geometry and Singularity Theory, as well as to their algorithmic computations.

The students are able to name the essential propositions of the lecture as well as to classify and to explain the connections. They understand the proofs presented in the lecture are able to comprehend and explain them.
