Topologie - 2019

Topics:

• What is the Fundamental group of the Möbius strip.

When two spaces have the same Fundamental Group? Def of Homotopy equivalent spaces and find the homotopy equivalence between the cirle and Mobius strip.

• exercise: you have (xn) sequence with limit x. Prove that the set containing only the sequence and the limit is compact.

I took a long time for the first part and unfortunately after there was no time left.

Sisto is calm and helps you if you make confusion.
