Learning outcome


At the end of the course, the student should:
- Be familiar with the basic notions of commutative algebra.
- Display knowledge and understanding of the course
topics and content at a level suitable for further studies in
commutative algebra and algebraic geometry.


At the end of the course the student is expected to be able
to follow and reproduce arguments at a high abstract level
corresponding to the contents of the course.


At the end of the course the student is expected to be
able to apply basic techniques and results to concrete examples.

5 hours lectures conducted as flipped classroom, (that is as discussions of the course material. Students are expected to participate in discussions of the course material during the flipped classrooms hours) and 3 hours exercises each week for 7 weeks.

Algebra 2 (Alg2) or similar.

Academic qualifications equivalent to a BSc degree is recommended.

Feedback by final exam (In addition to the grade)

Oral feedback will be given on students’ presentations in class. Individual feedback will be given in connection with the oral exam. Collective feedback will be given through comments by the TA on blackboard presentation by students at the exercise sessions.
