This was a continuation of the course Topology II in Sommersemester 2018, focused on homotopy theory. The main topics were the following.
- A brief recollection of some homotopy theory that was covered in the lectures Topology I and Topology II.
- Fibrations and cofibrations, homotopy (co)fibres.
- The Blakers-Massey theorem and the Freudenthal suspension theorem.
- Brown representability and Eilenberg-MacLane spaces.
- Postnikov and Whitehead towers, k-invariants.
- Quasifibrations and the Dold-Thom theorem.
- Serre classes and rational homotopy groups of spheres.
- Principal bundles, vector bundles, classifying spaces.
Here is a detailed outline of the topics covered in the lectures:
There were two exercise classes, taking place once per week, starting in the second week of the semester.
- Friday 10–12 — Daniel Brügmann — seminar room 1.008.
- Friday 12–14 — Benjamin Ruppik — seminar room 0.011.
The exercise sheets are uploaded here on Fridays. The general pattern is that exercise sheet n (uploaded on the Friday of the nth week of the semester, for positive n) should be handed in before the lecture on Monday afternoon of week n+2. Exercise sheets may be handed in jointly by at most three students.
The exams are written. The dates are the following.
- First exam: 9:00–11:00, Wednesday 6 February 2019, Kleiner Hörsaal, Wegelerstr. 10.
- Here is a list of the grade boundaries for the first exam.
- Klausureinsicht (exam review): 14:00–15:00, Thursday 7 February 2019, seminar room 0.011.
- Second exam: 9:00–11:00, Wednesday 13 March 2019, Kleiner Hörsaal, Wegelerstr. 10.
- Here is a list of the grade boundaries for the second exam.
- Klausureinsicht (exam review): 14:00–15:00, Thursday 14 March 2019, seminar room 0.011.
As usual, the requirements for admission to the exam are:
- Obtaining at least half of the credits from the exercise sheets (from sheets 1–11, each of which has 20 points available, so the threshold is at least 110/220 points).
- Presenting at least two exercises on the blackboard during the exercise sessions.
