Description

This lecture explores examples from Hatcher's book to demonstrate the use of the homotopy extension property for CW pairs, showing how certain topological spaces are homotopy equivalent. By examining the sphere S2 and the torus with attached discs, the instructor illustrates how to contract subcomplexes to obtain homotopy equivalences between different spaces.
