Topics

cohomology, cup product, Künneth theorems, manifolds, orientations, Poincaré duality, fiber bundles, fibrations

- A. Hatcher, Algebraic Topology
- T. tom Dieck, Algebraic topology (EMS Textbooks in Mathematics)

Prerequisites

This class is a direct continuation of my class "Topology I" from the winter term 2024/25. Prerequisites are point set topology (topological spaces, subspaces, quotient spaces, compactness, separation axioms); fundamental group; covering space theory; CW-complexes; higher homotopy groups; singular and cellular homology

Additional resources

I previously taught this class in the summer term 2021 during the covid pandemic. I have made the slides and videos that I produced then available on eCampus, so that they can serve as additional resources. To access the slides and videos, you must join the eCampus course "V3D2/F4D1 - Topologie II / Topology II". The contents may differ to some extent from the content of the videos.

Exercises

We provide weekly exercise sheets on Fridays, available here for download. The completed exercises have to be handed in 10 days later before the Monday lecture. Exercise sheets may be handed in jointly by at most three students.
