Competencies / intended learning achievements

Upon completion of this module, students have studied and understood 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.
