Competencies / intended learning achievements

Upon completion of this module, students have studied and understand the language and methods of commutative algebra, which is necessary to continue studying in the area of algebraic geometry, computer algebra and number theory. They have recognized how taking a higher point of view, that is, the abstraction of the problem, makes it possible at once to treat and solve completely different questions simultaneously. They understand the proofs presented in the lecture and are able to reproduce and explain them.

By completing the given exercises, the students have developed a skilled, precise and independent handling of the terms, propositions and techniques taught in the lecture. In addition, they have learned to transfer the methods to new problems, to analyze them and to develop solution strategies.
