NMAA05100U  CHANGED: Homological Algebra (HomAlg)

Volume 2018/2019
Education

MSc Programme in Mathematics

Content

Basic notions in module theory, tensor products of modules, exact sequences. Categories, functors, natural transformations, adjoint functors. Chain complexes and homology, resolutions, exactness of functors and derived functors.

Learning Outcome
  • Knowledge: To display knowledge of the course topics and content.
  • Skills: To be able to use the acquired knowledge to perform computations.
  • Competences: At the end of the course the student should
    • Be well versed in the basic theory of modules over a ring (direct sums and products, tensor products, exact sequences, free, projective, injective and flat modules.)
    • Understand the basic methods of category theory and be able to apply these in module categories (isomorphisms of functors, exactness properties of functors, adjoint functors, pushouts and pullbacks).
    • Have a thorough understanding of constructions within the category of chain complexes (homology, homotopy, connecting homomorphism, tensor products, Hom-complexes, mapping cones).
    • Have ability to perform calculations of derived functors by constructing resolutions (Ext and Tor).
    • Be able to interpret properties of rings and modules in terms of derived functors (homological dimensions, regularity).
    • Have ability to solve problems in other areas of mathematics, such as commutative algebra, group theory or topology, using methods from homological algebra.

5 hours of lectures and 3 hours of exercises per week for 9 weeks.
Credit
7,5 ECTS
Type of assessment
Continuous assessment
CHANGED in 2018/2019: The grade will be determined by 3 "closed book" in-class exams: Two 90 minutes multiple choice exams in weeks 3 and 6, and one 120 minutes written exam in week 9. The two multiple choice each count 25%, and the final 2-hour exam counts 50%.”
Aid
Only certain aids allowed

No books and no electronic aids are allowed for the exams. Personally created
handwritten notes on paper are allowed

Marking scale
7-point grading scale

External censorship
Re-exam

30 minutes oral examination with no aids or preparation time. The oral examination will cover the entire material of the course, including the three exercise sets.
