Exercises and Solutions
New exercise sheets will be posted here every Wednesday afternoon. The sheet is due the following Tuesday midday (12:00).
To submit your Homeworks, either upload them electronically on My, or if you want to submit a paper copy, upload an empty page to My (required for record) and submit a paper copy either bringing it to class on Monday or leaving it in the Assistants pigeon hole (floor K, on top of the mailing boxes).
Solutions to selected problems will be also posted here. Solutions to the other problems will be discussed during tutorial classes.

Some nice videos online:
- A proof of the Euler characteristic of sphere triangulations using dual graphs (video by Youtuber 3Blue1Brown)
- From a octagon to a double torus (short animation)
- From a 40-gon to a surface of g=10 (short animatin)
- Compactify/identifying the boundary of a disk to get a sphere (short animation)
- A visual proof that the projective plane contains a Moebius band (a visual solution to one of the Homeworks exercises!), online lecture with animations and 3D models;
- Video on the classification of surfaces statement showing connected sums visually, online lecture with animations and 3D models;

Testat: To be admitted to the exam, you need to submit 60% 'reasonable attempts' to the homework problems to be handed in (not 60% of credit points). Solutions do not need to be perfect nor fully correct, but you should show that you made a serious effort to work on the exercises that are marked as 'to be handed in'. You are welcome to discuss ideas in groups (do try first alone!). Each student should then write and submit his/her solutions independently. Homeworks can be submitted online (on My) or in paper copy (directly to the assistants).
Recordings: recordings are available to registered users from the UZH Swich system, under the Channel 'MAT701 Elements of Topology, HS 2022. To subscribe to the channel, click here.

Modul: 02.02.2023 9:00-12:00, Raum: Y24G45 Plätze: 446, Typ: schriftlich
Repetition: 07.09.2023 9:00-18:00, Raum: Y27H26 Plätze: 14, Typ: mündlich
The exam is written and will take place with closed books.
No cheat sheet is allowed.
The exam will consist mostly of exercises to solve (in the spirit of Homework problems), but theory questions concerning fundamental definitions and results will also be included.
During the exam, it will be possible to ask to have any of these definitions/results written down (of course loosing the points for the part of the question concerning the theory) in order to solve the rest of the exercise.
