Algebraic Topology 1

For this course, I will sometimes make use of other lecture notes, which have been written by Ieke Moerdijk and Moritz Groth for a course given at Nijmegen University. I gratefully acknowledge their courtesy in letting me use them.

The course starts on October 7th and it runs on Mondays (lectures) and Thursdays (exercises), from 17:20 to 18:50. The classes on the 14th and 17th of October will not run, but we will make them up later before the end of the course.


EXAM DATES: -January 15th (@K11 from 11am to 1:30 pm) [pdf, solutions]

- January 22nd (@K11 from 11am to 1:30 pm) [pdf, solutions]

- January 27th (@K2 from 10am to 12:30 pm) [pdf, solutions]

- January 30th (@K11 from 11am to 1:30 pm) [pdf, solutions]

This will be a written exam with similar exercises as the ones we have done during tutorials. We will also see some more exercises in the 6th to 10th week of January.
