AlgTop25: More on the fundamental group
Показать описание
This video continues our discussion of the fundamental group of a space. We show that the homotopy classes of closed loops from a fixed point on a space actually form a group. And the important cases of the torus and the projective plane are studied in some detail.
This is the 25th lecture in this beginner's course on Algebraic Topology, given by Assoc Prof N J WIldberger at UNSW.
