Description

This lecture focuses on proving the homotopy extension property for a pair of topological spaces, where one space is contractable. The instructor demonstrates how the quotient map from the original space to the space quotiented by the contractable subspace is a homotopy equivalence, providing a detailed proof with technical insights and examples.
