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 (e.g. 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 4 hours of exercises per week for 9 weeks.

In previous years Rotman: "An introduction to homological algebra" has been used.

Knowledge of basic group and ring theory (e.g, UCPH courses Alg1 and Alg2) and a solid knowledge of Linear Algebra (e.g., UCPH course LinAlg, and ideally also AdVec) is assumed. Basic point-set and algebraic topology (e.g., UCPH course Top and AlgTop) is helpful, but not assumed.

Academic qualifications equivalent to a BSc degree is recommended.

Type of assessment details
The grade will be determined by 3 "closed book" in-class exams: Two 90 minutes multiple choice exams during the first 8 weeks, and one 120 minutes written exam in week 9. The two multiple choice each count 25%, and the final 2-hour exam counts 50%.

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
