There is a theorem:If |K| is connected,abelianizing its fundamental group gives the first homotopy group of K.
How to abelianize a group? And how to understand this theorem more obviously?Can anyone show me an example to see it?
I myself will think this problem for more time because I learn it just now and haven't think it much.
Thank you!
