Topics in algebraic topology centered around the use of categories in homotopy theory and simplicial methods. Topics include simplicial sets, nerves of categories, classifying spaces, homotopy (co)limits, localization and completion.

Learning outcome
Knowledge: To display knowledge of the course topics and content, at the level of a beginning researcher.
Skills: To be able to use the acquired knowledge to perform computations.
Competencies: To be able to produce independent proofs in extension of the acquired knowledge.

In previous years lecture notes were used. It will be aimed to make these notes available from Absalon and/or the lecturers homepage.

Teaching and learning methods
4 hours lectures and 4 hours exercises per week for 9 weeks.

Academic qualifications:

Knowledge of foundational algebraic topology corresponding to roughly Chapter 1-5 in Hatcher's book "Algebraic Topology" is assumed (e.g., obtained thorough the UCPH courses AlgTop, HomAlg and AlgTopII).

Academic qualifications equivalent to a BSc degree is recommended.
