Because of scheduling problems and because this course is a follow up of Lecture 19215101 "Topologie III" by Elmar Vogt the dates of the two lectures will be as follows:
Both courses run on Tu 12-14, SR 031/A7 and Th 12-14, SR 140/A7(Hinterhaus)
Topologie III starts on 18.04. 2017 and ENDS on 01.06.2017;
Categories and Homotopy Theory STARTS on 06.06.2017 and ends on 20.07.2017.
The contents of both lectures are basic for (algebraic and geometric) topology, and we strongly recommend for students to take both as a single package.
